Gunfight Kills 2 Americans Who Trained Afghan Army.

KABUL, Afghanistan -- A seemingly routine training practice in marksmanship went fatally wrong on Tuesday when an Afghan Army sergeant turned his weapon on an American trainer and a gunfight began. When it was over, the sergeant, two American trainers and an Afghan soldier who had been standing nearby lay dead. The fight, which also wounded a NATO soldier, occurred near the northern city of Mazar-i-Sharif at a training center for Afghan soldiers named Camp Shaheen, according to a statement from the NATO command and an Afghan defense official.
