Nineteen civilians and one member of the Malian security services were killed during the siege, United Nations spokesman Olivier Salgado told NBC News. Three jihadi attackers were also dead, the spokesman said.

But as Malian special forces and police searched the 190 rooms and suites at the Radisson Blu hotel for more bodies, officials warned the death toll could rise.

By 1 p.m. ET, the bloody siege in the capital of Bamako appeared to be over, a hotel receptionist manning the front desk told NBC News.

About a dozen Americans were among those rescued and there are no reports that any U.S. citizens were killed or injured, State Department spokesman John Kirby said. It was unclear how many Americans were at the sprawling pink and cream colored hotel when the attack occurred, Kirby said.

"The United States condemns in the strongest terms today's terrorist attack on the many Malian and international guests and employees of the Radisson Blu Hotel in Bamako," the White House said in a statement. "We can confirm that the attack has ended, and we continue to coordinate with U.S officials on the ground to verify the location of all American citizens in Mali."

An al Qaeda-affiliated terrorist group claimed credit for the attack, Reuters reported. NBC News could not immediately confirm that.

The mayhem in Mali came just days after the Iyad Ag Ghaly, the leader of the al Qaeda linked militant group Ansar Dine, called for attacks on France and its interests in the African country.

The deadly drama began around 7 a.m. when invaders shouting "Allahu Akbar," or "God is great" in Arabic, burst inside the hotel and opened fire on the guards and quickly took dozens of captives, Mali army commander Modibo Nama Traore told The Associated Press.

In the chaos, many of the guests managed to escape, but scores more fell into their clutches, the AP reported.

"The hotel is locked down and there is no possibility to go out or come in," a spokesman for Carlson Rezidor, owners of the hotel, told NBC News at the time.

Monique Kouame Affoue Ekonde, an Ivorian, recounted how she and six other people — including a Turkish woman — were escorted out by security forces as the gunmen rushed "toward the fifth or sixth floor."

Shortly after the shooting started, a U.S. special forces soldier in town for a UN peacekeeping conference rushed to help Malian troops move the escapees to safety, officials said.

The raid on the Radisson Blu, which is popular with foreigners and frequently used by airline crews, came a week after terrorists killed 130 people in Paris.

In response to Friday's terror, France announced the immediate dispatch of 50 elite counter-terrorism police to the country.
