|Prosecutors say Uka acted alone in carrying out the attack on US servicemen at Frankfurt airport [Reuters]
A Kosovo man has told a German court he regrets shooting dead two US airmen and wounding two more at Frankfurt airport in March, and does not understand why he did it.
Charged with two counts of murder and three of attempted murder, Arid Uka, 21, a Kosovo Albanian who grew up in Germany, told the court he was influenced by Islamist "lies and propaganda that blinded me".
"What I did was wrong, but I cannot undo what I did," Uka said at the opening of his trial on Wednesday.
Prosecutors believe Uka acted alone in carrying out the attack in Germany, if found guilty he could face a life sentence.
Uka told the court he felt he had to act after he was shocked by a video the night before the attack that appeared to show US soldiers raping Muslim women.
In fact, the video was a scene from Brian De Palma's anti-war film, Redacted.
"I had to do something, I had these pictures in my head," said Uka when questioned by prosecutors.
"I thought what I saw in that video these people would do in Afghanistan, I killed two people and opened fire on three others, today I can't understand myself how I could have acted this way."
He said some people viewed his actions as good but they were subject to the same "lies and propaganda that blinded me".
Uka was working at the airport's international postal centre when he fired on the airmen at point-blank range with a 9mm pistol.
The attack shocked US citizens and US President Barack Obama expressed outrage.
German prosecutors believe Uka acted alone but he refused to tell the judge where he obtained the pistol.
Prosecutors have described how Uka walked up to airmen boarding a US army bus and asked one of them for a cigarette.
After establishing the soldiers were heading to fight in Afghanistan, Uka shot the 25-year-old man in the back of the head.
Prosecutors say he then boarded the bus, shouted "Allahu Akbar" or "God is great" and shot dead a 21-year old airman sitting in the driver's seat. He wounded two others and pulled the trigger on a fifth target when his gun jammed.
The airmen on the bus had just flown in from Britain and were about to travel to the nearby US airbase at Ramstein, a hub for operations in Iraq and Afghanistan.
A panel of three judges will deliver the verdict at the end of the trial, scheduled to last until January.
