Four US troops serving with NATO were killed Sunday in a suspected insider attack in southern Afghanistan, in what is thought to be the second deadly instance this weekend of Afghan policemen turning on their allies.
Four U.S. troops fighting with the NATO-led alliance were killed in another suspected "insider" attack in southern Afghanistan on Sunday, bringing the total number of deaths this weekend caused by Afghans turning on their allies to six.
Four troops were found dead and two wounded when a response team arrived at the scene from a nearby checkpoint, a spokesman for the coalition said. A Pentagon spokesman confirmed that the four dead were Americans.
One of the six members of the Afghan National Police (ANP) operating the observation post with six coalition troops was also found dead, while the other five had disappeared.
"The fighting had stopped by the time the responders arrived," said Major Adam Wojack, a spokesman for the NATO-led coalition.
The attack came a day after two British soldiers were shot dead by an Afghan policeman while returning from a patrol in the southerly Helmand province, one of the strongholds of the Taliban-led insurgency.
