An Israeli military court on Wednesday found a young Israeli soldier, Sgt. Elor Azaria, guilty of manslaughter for “needlessly” killing a wounded Palestinian assailant last March, in a case that has divided Israeli society. Azaria, 20, shot the Palestinian, Abdul Fattah al-Sharif, in the head as he was lying on the ground after being disarmed of his knife. The incident occurred in the occupied West Bank after another soldier had been stabbed. A video captured by a Palestinian shows a soldier identified as Azaria fatally shooting Sharif from several yards away. The court rejected Azaria’s claim that he shot Sharif because he could still pose a threat, possibly hiding a suicide belt.
