Five people were confirmed killed in chaos at Kabul airport on Monday as U.S. troops guarded the evacuation of embassy staff.

This is coming a day after the Taliban seized the Afghan capital and declared that the war was over and peace had prevailed.

Eye witnesses said it was not immediately clear how the victims died.

A U.S. official said troops had fired in the air to deter people trying to force their way onto a military flight that was set to take U.S. diplomats and embassy staff out of the fallen city.

One witness, waiting for a flight out of the city for more than 20 hours, said it was unclear if the five had been shot or killed in a stampede.

The chaos came as Taliban officials declared the war over and issued statements aimed at calming the panic that has been building in Kabul as the militants, who ruled from 1996 to 2001, routed the U.S.-backed government’s forces.

President Ashraf Ghani fled from the country on Sunday as the Islamists entered Kabul virtually unopposed, saying he wanted to avoid bloodshed.

It took the Taliban just over a week to seize control of the country after a lightning sweep that ended in Kabul as government forces, trained for years and equipped by the United States and others at a cost of billions of dollars, melted away.
