Frankfurt: A gunman fired shots at US military personnel on a bus outside Frankfurt airport on Wednesday, killing two people and wounding two before being taken into custody, authorities said.
Kosovo's interior minister told The Associated Press that German police have identified the gunman as a Kosovo citizen.
The attack came as the bus sat outside Terminal 2 at the airport, Frankfurt police spokesman Manfred Fuellhardt said.
The two killed were the bus driver and a passenger, and one person suffered serious wounds and another one light injuries, Fuellhardt said.
The spokesman could not confirm whether any of the casualties were US military personnel.
The US Army in Europe referred calls to the Air Force, but a spokeswoman said she could not immediately confirm that the casualties were airmen nor give any details of the incident.
The bus had a US government license plate marked "AF" for Air Force.
Still, German Chancellor Angela Merkel told reporters in Berlin that two American soldiers had been killed, as she condemned the "terrible incident."
"We'll do everything possible to find out what happened," she pledged.
At the airport, taxi cab driver Salimi Seraidon said he was sitting at a stand about 200 yards (meters) away when the attack took place, and that it was over quickly as police rushed onto the scene.
"We just heard the shots," he said.
Fuellhardt said he could not give out any information on the suspect, but authorities in Kosovo said he was a citizen of the tiny Balkan nation.
Kosovo Interior Minister Bajram Rexhepi said in an interview that German police have identified the suspect Arif Uka, a Kosovo citizen from the northern town of Mitrovica.
"This is a devastating and a tragic event," Rexhepi said. "We are trying to find out was this something that was organised or what was the nature of the attack."
Spokesmen for the Pentagon and the Air Force in the US had no immediate information on the incident.
While German police had no immediate information on what could be behind the shooting, a member of the US House Homeland Security Committee, Rep Patrick Meehan, said in Washington that it looked like a terrorist attack.
