BAGHDAD, Feb 5 (Reuters) - U.S. forces have begun reducing their numbers in Iraq after Iraqi authorities declared "victory" over Islamic State, an Iraqi government spokesman said on Monday.
Iraqi forces backed by a U.S.-led international coalition last year captured all the territory that fell under Islamic State control in 2014 and 2015, including the northern city of Mosul, which served as the militants' de facto capital.
"The American forces have begun reducing their numbers as victory has been achieved over Daesh," the spokesman told Reuters. "Coordination continues, to maintain (U.S.) assistance to the Iraqi forces in accordance with their requirements."

Smoke rises after an air strike during fighting between members of the Syrian Democratic Forces and Islamic State militants in Raqqa, Syria, August 15, 2017. Zohra Bensemra: "Access to the frontline of the battle for Raqqa in Syria was more limited than during the battle for Mosul in Iraq. Raqqaï¿½ battle was different also from Mosulï¿½ because we saw very few civilians who managed to escape. We didnï¿½ have daily access. We were often posted in buildings used as a command base or observation point. From there we could photograph troop movements and smoke after air strikes. On this day, we were refused permission to go to the frontline. They said it was too dangerous and there was no armoured car. Even so, we decided to wait with the hope of advancing towards the combat zone. We were sitting with SDF members when we learned from one of the officers that there was going to be an air strike. To our surprise, the target building was close-by." REUTERS/Zohra Bensemra/File Photo
A member of the Syrian Democratic Forces calls his comrades during the fighting with Islamic State fighters in Raqqa, Syria, August 14, 2017. Zohra Bensemra: "The Reuters team waited almost all day behind Syrian Democratic Forces members who were fighting Islamic State in Raqqa to lead us into this building. They had posted themselves there temporarily. They took it after fierce fighting. It was just at very short distance from the Islamic Stateï¿½ position. Whenever a building or a district was taken from the jihadists, the soldiers would exhibit their black flags like spoils of war. That day they found two black flags. I heard them arguing with each other over whether to burn them. Some soldiers refused saying that the words on the flag contained text from the Koran and was thus sacred."

Internally displaced Syrian children who fled Raqqa city stand near their tent in Ras al-Ain province, Syria, January 22, 2017. Rodi Said: "Whenever I photograph children who were displaced by war, I always think of my only daughter, placing myself in a situation where any father watches his children suffer from hunger, the cold and homelessness. I always strive to convey the situation to the world through a photograph and that's the most I can offer as a photojournalist." REUTERS/Rodi Said/File Photo

Kurdish fighters from the People's Protection Units (YPG) fire rifles at a drone operated by Islamic State militants in Raqqa, Syria, June 16, 2017. Goran Tomasevic: "ISIS uses drones to monitor Kurdish fighters and drop bombs at their positions. On a few occasions I ran into a house with fighters because of drones. On one occasion a bomb from a drone landed near a house where I was hiding with the rest of our team and YPG fighters. The biggest challenge in Raqqa was very limited access and the heat. The temperature during the day was around 50 degrees Celsius." REUTERS/Goran Tomasevic/File Photo
A civilian prays after she was rescued by fighters of Syrian Democratic Forces from the stadium after Raqqa was liberated from the Islamic State militants in Raqqa, Syria, October 17, 2017. Erik De Castro: "The day Raqqa was liberated I arrived at the frontline and noticed there were no more plumes of smokes from air strikes and no more sounds of gunfire. I took pictures of dozens of Syrian Democratic Forces as they marched towards the stadium which was Islamic State fighters' last stand. The atmosphere was euphoric, especially when fighters were cheering while sitting on top of armoured vehicles and a tank parading around the infamous roundabout of Dawwar al-Naim where the Islamic State militants used to execute people and hang their heads. I then noticed SDF Fighters running towards the far end of the stadium and followed them. I took pictures of an elderly woman being carried by the fighters. They gave her water and food, the woman said she was hiding in the rubble of a house beside the stadium during the fighting and air strikes. She also said other members of her families, two daughters and a son did not survive. After being rescued, she was crying along a sidewalk and praying." REUTERS/Erik De Castro/File Photo

Local Villagers made a makeshift crossing as the canal was dividing the village." REUTERS/Goran Tomasevic/File Photo
Kurdish fighters from the People's Protection Units (YPG) run across a street in Raqqa, Syria, July 3, 2017. Goran Tomasevic: "They were members of Kurdish YPG militia. They were running across the street because ISIS fighters' positions were nearby. I shot the picture in a last day of my assignment. I was lucky to have that picture as YPG fighters were giving very restricted access to media." REUTERS/ Goran Tomasevic/File Photo
Iraqi Special Operations Forces (ISOF) gather during an operation to clear the al-Zirai district of Islamic State militants in Mosul, Iraq, January 19, 2017. Muhammad Hamed: "In this picture, we were on a tour with the head of the Rapid Response Unit General Al Assadi when the soldiers decided to walk into a damaged mosque. The area we were in was only recently liberated. I was in the same mosque the day before and the Federal Police had shot down an Islamic State drone carrying explosive just outside. At first I was hesitant to go deep into the mosque, as I worried that some explosives may be left behind. But when I saw the lights coming in through the broken windows and after getting okay from my security advisor I decided to go in for the picture." REUTERS/Muhammad Hamed/File Photo
Iraqi Special Operations Forces arrest a person suspected of belonging to Islamic State militants in western Mosul, Iraq, February 26, 2017. Alaa Al-Marjani: "I spotted four suspected Islamic State militants picked out of a group of displaced people by Iraqi soldiers. The suspects had been identified by civilians working with the security forces and wearing masks to protect themselves from possible reprisal by IS. The suspects including the man in this picture were then tossed into the bed of a pickup truck. My picture was significant for our story because it helped illustrate how some militants had secreted themselves among fleeing civilians in hopes of evading capture. Some of them trimmed their bushy beards and changed their clothes in efforts to blend in. I had been covering developments on another front when I saw on social media that a large group of refugees was heading to this location. Not much was happening where I was so I changed cars and headed to the refugee gathering point. The way the suspects were being treated was abnormal so I felt it was very important to document this in pictures. After I took this picture, a military intelligence officer tried to seize my camera and send me away. I was working together with a Reuters correspondent and security adviser, so the officer eventually desisted and allowed me to take further photos. It can be difficult controlling your feelings when taking pictures right at the scene of gunfire and explosions. There is a lot of human suffering, but also a lot of competition with other agencies to get the best photograph in the shortest period of time. My camera is very modern but internet access needed to file our pictures is difficult because most communications towers in the region are down." REUTERS/Alaa Al-Marjani/File Photo
Relatives carry the bodies of civilians killed in air strike, during a battle between Iraqi forces and Islamic State militants, in Mosul, Iraq, March 17, 2017. Youssef Boudlal: "Early that morning I was following some displaced Iraqi people from different areas in Mosul fleeing their homes during clashes between Iraqi forces and Islamic State militants in the city of Mosul. I saw a few people transporting their belongings on trolleys. I thought it was just food and a few clothes, but the closer they got the more the smell was unbearable and I discovered that they were carrying the bodies of civilians who were killed a few days ago in air strikes."

Iraqi woman Lila Ayed, 37, whose husband was killed and two of her daughters went missing during the fighting in Mosul, waits with her children to cross the Tigris river by a military boat after the bridge was temporarily closed, south of Mosul, Iraq, May 4, 2017. Suhaib Salem: "In the early morning on my way to Mosul I found long line of cars. I went out of the car to check and found that the bridge over the Tigris river had been temporarily closed in front of all displaced people who fled their houses during the fighting in Mosul. Suddenly I saw Lila and her daughters standing by the river waiting. They were very sad. I came very close to Lila and started talking with her. She told me that her husband was killed, two of her daughters were still missing and that she was going back to Mosul to look for them. I took some pictures of the family while they were urging an Iraqi soldier to let them enter a boat. I followed them on a military boat, crossing the river to the western side of Mosul. I don't know what happened to her after." REUTERS/Suhaib Salem/File Photo
Displaced Iraqi women who just fled their home, rest in the desert as they wait to be transported while Iraqi forces battle with Islamic State militants in western Mosul, Iraq, February 27, 2017. Zohra Bensemra: "I took this picture in a desert on the outskirts of Western Mosul of 90-year-old Khatla Ali Abdallah after she fled the battle for Mosul. Her fearful eyes red with fatigue, Khatla was so exhausted she could not stand or even sit properly. She looked to me like she had not eaten or drank water for a long time. The moment was so emotional that I had tears in my eyes when I photographed Khatla. I felt bad because I could not do anything for her apart from taking pictures to show the world the agony and torment of people trying to flee Mosul to safety. I was sad too, imagining this woman as my own grandmother and feeling helpless to make her comfortable. When you face such a moment, you always think that it could happen to anyone of us. But despite all, Khatla looked beautiful to me, almost as if every wrinkle on her face told a story. I was fortunate to find her a few days later in a refugee camp after showing people my photograph of her. She has survived decades of turbulence in northern Iraq. She told me "the fighting there is the worst I have ever seen". She had been carried across the desert by her grandsons, under sniper and mortar fire, one of thousands who braved the difficult and dangerous journey out of Islamic State's shrinking stronghold in western Mosul. Khatla made me smile when she expressed her remorse about her 20 chickens she had to leave behind. She had looked after them even while hiding from crossfire in her house's basement. Despite all the terror she experienced under IS rule, it had not destroyed her humanity - she said, 'Even animals deserve life.'" REUTERS/Zohra Bensemra/File Photo
An altar of a damaged church is seen in the town of Qaraqosh, south of Mosul, Iraq, April 11, 2017. Marko Djurica: "In April 2017 I was on an assignment in Iraq, covering the battle between Iraqi forces and Islamic State fighters. Every day the Reuters team would go to the frontline from Erbil to west Mosul where the fights were going on. Each day on the road we would pass the small town of Qaraqosh. Once home for about 50,000 mostly Iraqi Christians, now it was completely empty, a ghost town. Iraqi forces kicked out Islamic State fighters but citizens were still afraid to go back to their homes. The town once had 12 churches with one more than 1000 years old. Now all were destroyed or badly ruined. Burnt-out altar of a church was one of the images I took that made me very sad."

A boy who just fled a village controlled by Islamic State fighters cries as he sits with his family on a bus before heading to the camp at Hammam Ali south of Mosul, Iraq, February 22, 2017. Zohra Bensemra: "As the battle between Iraqi forces and Islamic State fighters to liberate the west of Mosul became increasingly ferocious, the flows of civilians fleeing their city intensified day after day. Refugee camps were filling up quickly. The child was crying because he was exhausted and hungry. He sat with other displaced civilians in one of three buses that were transporting them to a camp. But the Federal Police brigade in charge of sheltering them were struggling to find places in the camps. They had made checks but all of them were full. I took this picture at sunset. I fear the displaced families were still far from the end of their ordeal." REUTERS/Zohra Bensemra/File Photo
ATTENTION EDITORS - VISUAL COVERAGE OF SCENES OF INJURY OR DEATH Bodies of alleged Islamic state militants are seen in a field south of Mosul, Iraq, May 15, 2017. Danish Siddiqui: "Our team was coming back from frontlines in western Mosul when we decided to search for dead bodies that our text reporter had heard about. After asking a few locals we took a small road near a highway and after a few kilometres I spotted bodies lying by the roadside. I saw that the men were blindfolded and were shot from at close range. There were several spent bullet casings lying near the bodies. This picture was taken a few meters away from the rest of the bodies. We could only spend few minutes there as we didn?t want to attract the attention of passing military vehicles." REUTERS/Danish Siddiqui/File Photo
People walk in front of the remains of the University of Mosul, which was burned and destroyed during a battle with Islamic State militants, in Mosul, Iraq, April 10, 2017. Marko Djurica: "On April 10, a Reuters team entered eastern Mosul to work on a story about the the city's destroyed university, once a centre for education in northern Iraq. On arrival, I was struck first by the huge size of the campus, then by the scale of destruction. At least 10 large buildings and some smaller ones had been more or less reduced to rubble. The entrance was guarded by Iraqi soldiers, cleaning their guns and drinking tea. I saw people trying to carry furniture and equipment out from what was once the chemistry department in a burnt-out building. It turned out these men were professors who had taught there and had now volunteered to save whatever could be salvaged. As I walked around taking pictures I met more teachers trying to clean up or just gloomily contemplating the devastation. It was emotional for them as they knew there was no chance the university would be the same again anytime soon." REUTERS/Marko Djurica/File photo
A member of Iraqi Federal Police crosses from one house to another through a hole in the wall at the frontline in the Old City of Mosul, Iraq, June 27, 2017. Alaa Al-Marjani: "We were on a media tour guided by the Iraqi Federal Police forces in the old city of Mosul. We got out of vehicles and started walking. The forces were advancing rapidly through holes they had made in the walls of buildings to avoid being targeted by Islamic State fire. I was happy that I got access to get my pictures and return safe." REUTERS/Alaa Al-Marjani/File Photo SEARCH "POY IS" FOR THIS STORY.
A member of the Iraqi Federal Police rests at the frontline in the Old City of Mosul, Iraq, June 28, 2017. Ahmed Jadallah: "I left Erbil early in the morning bound for Mosul with our multimedia team and security adviser in an armoured car. After an almost three-hour drive, passing many Kurdish Peshmerga and Iraqi military checkpoints, we crossed the Tigris river and reached the headquarters of the Iraqi Federal Police in western Mosul. An hour later a Federal Police convoy escorted us to the frontline in the Old City. There, while covering a battle between Federal Police and Islamic State, I passed the soldier in the photograph. He was taking a rest in a temporarily more sheltered spot and draped himself with a net to keep away clouds of insects that had been attracted by dead bodies and raw sewage nearby. The picture shows the rough conditions of the frontline where there is no decent place to sleep while the fighting carries on. Just one mistake of walking down a street in the wrong direction could have landed me in the deadly hands of Islamic State. The most important thing is to stay out of sight of Islamic State snipers and drones. Of all the wars I have covered in various countries, Mosul has been the worst." REUTERS/Ahmed Jadallah/File Photo
Members of the Iraqi Counter Terrorism Service (CTS) forces look at the positions of Islamic State militants during clashes in western Mosul, Iraq, May 15, 2017. Danish Siddiqui: "In May, I was accompanying a senior commander of Counter Terrorism Service, an elite Iraqi security force trained by the U.S., during the battle to take control of Western Mosul. We arrived at a small house on the frontline after walking through holes in the walls between homes. Islamic State snipers were firing a few hundred meters away. The people who once lived there departed quickly, leaving clothes and toys scattered across the floor. The next inhabitants left hollow shell casings. The CTS had taken over the house a day ago. The curtain was a bed sheet. They stood behind it to identify enemy snipers and watch one of their own. It's a quiet picture that tells of even the most uneventful of moments on the front, when nothing may happen, and everything is possible." REUTERS/Danish Siddiqui/File photo
An Iraqi soldier from the 9th Armoured Division gives drops of water to a dehydrated child rescued earlier by soldiers at the frontline, during the ongoing fighting between Iraqi forces and Islamic State militants near the Old City in western Mosul, Iraq, June 13, 2017. Erik De Castro: "We arrived at the frontline with the 9th Iraqi army division and went up on a rooftop to take pictures of the Grand al-Nuri mosque and its landmark minaret, still in the hands of Islamic State in western Mosul. That's when we spotted civilians fleeing the tightening noose around the Islamic State militants by scrambling through a hole in a wall of a school across the road. The day was blazing hot, with temperatures reaching 40 Celsius with no breeze. The people emerging from western Mosul into the relative safety of government-held territory were suffering from heat exhaustion. With mortar shells exploding all around, an Iraqi soldier passed one small boy of probably no more than seven through the hole, unconscious, his head lolling back, his gaunt-looking body unnaturally hot. Tim, our security adviser, received him and, fearing the boy was suffering from dangerous heat stroke, carried him across the broken ground to find shade. The boy came round and started crying, and soldiers came to pour water on his head, chest and feet to cool him down. He gulped at the sips they gave him to drink and they found him a blue-coloured rug to lie on. An infant in a similar condition was then handed through the hole in the wall and placed beside the boy on the rug. Soon afterwards, the mother of the boy made it through the hole."

Iraqi rapid response members fire a missile against Islamic State militants during a battle with the militants in Mosul, Iraq, March 11, 2017. Thaier Al-Sudani: "This attack came in the middle of a battle when Iraqi forces were trying to recapture the regional government compound from Islamic State. I was taking pictures of clashes at Mosul's antiquities museum when we spotted an Islamic State drone in the air above us. We dropped to the ground for fear of being attacked by a rocket. I cut my hand and we returned to the car to treat it. When we got there, I saw Iraqi forces firing rockets nearby at an IS target beyond our field of vision, so I resumed taking photographs. I thought this photo was a strong one that expressed the terrible violence of battle. It is another world covering wars compared with news conferences. There is 100 percent danger, and the internet we need to transmit pictures is poor or non-existent." REUTERS/Thaier Al-Sudani/File Photo
ATTENTION EDITORS - VISUALS COVERAGE OF SCENES OF DEATH OR INJURY Iraqi Federal Police and a man carry a civilian, injured while opening a booby-trapped shop in Tayaran district, as Iraqi forces battle with Islamic State fighters in western Mosul, Iraq, March 12, 2017. Zohra Bensemra: "Iraqi forces were pushing Islamic State fighters in western Mosul back towards the old city. The Iraqi forces had to find a way to help civilians escape. The Mosul airport road was one way out. Reuters had a team there. Civilians arrived in small groups. We were waiting when we saw an Iraqi Humvee coming down the hill from a liberated district carrying wounded. It stopped in front of an ambulance. I photographed Iraqi Federal Police members carrying victims. I tried to find out what happened but nobody seemed to be sure. A second Humvee arrived with more victims. Someone said they had tried to shelter from the sun, waiting for humanitarian aid, in a shop but the shopï¿½ shutter was booby-trapped. It exploded." REUTERS/Zohra Bensemra/File Photo
A man cries as he carries his daughter while walking from an Islamic State-controlled part of Mosul towards Iraqi special forces soldiers during a battle in Mosul, Iraq, March 4, 2017. Goran Tomasevic: "Both screaming in terror, a father and the young daughter he cradled in his arm fled through the rubble-strewn streets of Wadi Hajar, transformed in a flash into a battleground between Islamic State fighters and Iraqi special forces. They and their neighbours - some wearing rubber sandals, some barefoot - were running from an IS counter-attack in this part of Mosul, dodging gunfire as the militants closed in. When they reached the special forces lines, males were ordered to lift their shirts to prove they weren't suicide bombers. Some had to take off their clothes or show their belts, though not those carrying children. The father was so beside himself, so panicked. It was obvious because he had a short shirt on and was carrying a child that he wasn't Islamic State." REUTERS/Goran Tomasevic/File Photo

The United States had more than 5,500 troops in Iraq at the height of the battle of Mosul in July 2017, making up about half the total force deployed by the coalition in the country.
A coalition spokesman declined to confirm or deny that the drawdown had begun. "It is our intent to publish a release whenever we have forces moving out of the theater," the spokesman, U.S. Army Col. Ryan Dillon, told Reuters.
"Continued coalition presence will be conditions-based, proportional to the need and in coordination with the government of Iraq," he said.
