NATO did not initially identify the nationality of the two soldiers killed, but reports from Afghanistan said they were both American.
The numbers show a sharp rise from green-on-blue attacks in prior years, as the incidents have turned into a major concern surrounding the NATO plan to hand off security control to the Afghans by 2014.
In southern Afghanistan’s Helmand Province, meanwhile, 17 Afghans were beheaded Sunday evening by the Taliban, including two women, according to the Los Angeles Times.
Afghan officials said that the civilians had been in a private home listening to music and dancing when the Taliban attacked, and that the incident occurred in an area of Afghanistan controlled by the Taliban.
There were also initial reports that 10 Afghan soldiers were killed at an Army checkpoint in another part of Helmand, and five more were kidnapped or might have defected, according to the Times. The Taliban also claimed responsibility for that attack.
