KABUL, Afghanistan – An Afghan soldier turned his gun on American troops at a checkpoint in the country’s east, killing two Americans and at least two fellow members of Afghanistan’s army in a shooting that marked both the continuance of a disturbing trend of insider attacks and the 2,000th U.S. troop death in the long-running war, officials said Sunday.
The string of insider attacks is one of the greatest threats to NATO’s mission in the country, endangering a partnership key to training up Afghan security forces and withdrawing international troops. . .
