(AP Photo/Abdul Khaleq) (Newser) – Two more NATO service members were shot and killed today in the latest "green on blue" attack to hit Afghanistan. The British troops were killed in front of the main gate of a NATO base in southern Afghanistan by a shooter who has reportedly served in the Afghan army for four years, the AP reports. He was shot and killed after coalition forces returned fire. The Afghan soldier, who arrived at the gate in an army vehicle, was able to get close to the British troops by claiming that he had been assigned to provide security for a delegation of government officials from Kabul who were visiting the base today, explains an Afghan army official. "He got close to the foreign troops—three or four meters—and he opened fire," he says. The Taliban claims the shooter had told the group of his plans. The attack brings this year's green-on-blue death toll to 15.
