Israeli troops killed two suspected Palestinian militants in the West Bank, a day after Palestinians in a Gaza refugee camp buried seven people they say were killed in a deadly air attack. The Israeli military and Palestinian witnesses offered conflicting versions of the strike in Gaza. Palestinians said Tuesday that the seven dead, including an 11-year-old boy, were all civilians killed by an Israeli missile fired into a crowd at the Nusseirat refugee camp the night before. The Israeli army said, however, that militants and some civilians had been struck and released a video indicating there was no one on the street near the vehicle targeted in the attack.
