An American citizen was killed and another injured when a gunman opened fire on them in Saudi Arabia's capital.
The shooting in Riyadh, near King Fahd Stadium, took place just after 2:30 p.m., according to the government-run Saudi Press Agency. No identities have yet been released, but the suspect was immediately arrested.
One person was pronounced dead at the scene and another rushed to a nearby hospital with serious injuries, authorities said.
The gunman opened fire on the two U.S. citizens while they were at a gas station, police said.
Early reports and Twitter chatter suggested the shooter may have been affiliated with the ISIS terror group, but an al-Arabiya report late Tuesday afternoon debunked the theory.
Sources told al-Arabiya the shooting was the result of a previous dispute between the suspect and the two Americans.
Security forces immediately returned fire and injured the gunman before bringing him into custody.
Pictures from the scene showed police swarming the gas station in question.
U.S. officials have yet to address the killing.
This is a breaking story. More information will come as it is made available.
