The apparent mass murder of Afghan schoolchildren, including one as young as 11, by U.S.-led troops, was virtually blacked out in the American media. The Taliban suicide attack that killed a group of CIA agents in Afghanistan was big news in the U.S. over the past week. The attack took place on a base that was directing U.S. drone aircraft used to attack Taliban leaders. The airwaves and front pages were filled with sympathetic stories referring to the fact that the female station chief, who was among those killed, was the "mother of three children." But the apparent mass murder of Afghan school children, including one as young as 11 years old, by U.S.-led troops, was pretty much blacked out in the American media. Especially blacked out was the claim by UN investigators that the students had not just been killed but executed, many of them after having first been rousted from their bedrooms and handcuffed.
