Eyewitnesses in Kabul said some casualties of Thursday's airport attack were victims of gunfire by foreign forces, reported CMG reporter Obaidullah Musaferzada from Kabul.

"I was not injured by the explosion. American soldiers shot at us," said one of the injured.

"I don't remember much of what happened. It wasn't a lot of casualties (caused by the explosion). It was U.S. soldiers shooting and using tear gas that caused a lot of casualties," he told CMG reporter.
