Mark Memmott, writing on NPR’s news blog “The Two-Way,” reports on the latest attack by Afghanis posing as allies of coalition force. From Three U.S. Troops Killed In Latest ‘Green On Blue’ Attack:

“Three U.S. Forces-Afghanistan service members died following an attack by an individual wearing an Afghan uniform in southwest Afghanistan today,” according to a statement from the International Security Assistance Force – Afghanistan.

NPR’s Soraya Sarhaddi Nelson, who is in Kabul, says more than one individual in an Afghan military or police uniform may have done the shooting. She’s reports that “a senior Afghan police official” said the Americans were invited to a dinner and that during the meal several police recruits stood up and opened fire.

The New York Times writes that “Muhammad Sharif, the governor of Sangin District of Helmand Province, where the killings took place,” said it was a local police commander who invited the Americans “to eat dinner at his check post on Thursday.”

There’s been a claim of responsibility from someone saying he speaks for the Taliban.

CNN notes that today’s attack “came a day after Secretary of State Hillary Clinton condemned an attack in the eastern Kunar province that killed USAID Foreign Service Officer Ragaei Abdelfattah, three ISAF service members and an Afghan civilian, and injured a State Department Foreign Service officer. That led Clinton to issue a statement “strongly” condemning the attack — but adding that “it strengthens our resolve to continue working with the Afghan people to build their economy, democratic institutions, rule of law, and security so that Afghanistan can stand on its own as a stable, secure, and increasingly prosperous country.”
