3 American Contractors Killed in Shooting at Kabul Airport

— -- Three American contractors were killed in a shooting incident at the international airport in Kabul today that may have involved an Afghan security officer at the airport, U.S. military officials said.

“We can confirm that there was a shooting incident at North Kabul International Airport complex 29 January at approximately 6:40 p.m. [local time]," according to the U.S. military in Afghanistan. "Three coalition contractors were killed as was an Afghan local national."

The three Defense Department contractors were Americans, a U.S. official said, noting that the shooter was wearing the uniform of an Afghan national policeman, but it was unclear if he was actually a member of the Afghan security forces or not. The shootings were on the civilian side of the airport, the official said.

The incident is under investigation, the official said, adding that it is also unclear if the Afghan listed as a fatality is someone other than the shooter who was shot dead by the security team at the airport.
