Gunman kills two US airmen at Frankfurt airport

FRANKFURT, (Reuters) – German police arrested a man  today after two U.S. airmen were shot dead and two  wounded in an incident on a U.S. Army bus at Frankfurt airport,  authorities said.
Security round the airport was tightened and an  investigation into the “terrible, senseless crime” was under  way, said Boris Rhein, interior minister for Hesse state.
“Whether the incident was linked to terrorism I cannot say  at this stage,” he told reporters.
The suspected gunman was apparently a Kosovo national, he  said. Police said he was 21.
A spokesman for Frankfurt airport operator Fraport said the shooting took place in a U.S. Army bus in front of  Terminal 2.  U.S. President Barack Obama said he was outraged by  the attack.
Authorities in Kosovo believed they knew the identity of the  suspected gunman but could not confirm it yet, Kosovo Interior  Minister Bajram Rexhepi told Reuters in Pristina.
A police official identified the man as Arif Uka from the  city of Mitrovica but no official confirmation was given yet.
