JERUSALEM (Reuters) – Israel’s defense minister rejected yesterday calls for an inquiry into the killing of 15 Palestinians by the military during a Palestinian demonstration that turned violent on Friday at the Gaza-Israel border. Hamas, the dominant Palestinian group in Gaza, said five of the dead were members of its armed wing. Israel said eight of the 15 belonged to Hamas. UN Secretary-General Antonio Guterres has called for an independent investigation into Friday’s bloodshed. But Defense Minister Avigdor Lieberman said Israeli soldiers only did what was necessary. “I think all our soldiers deserve a medal. As for a commission of inquiry – there won’t be one,” he said. On Saturday, Palestinian officials said the Israeli troops used live ammunition and rubber bullets against Palestinian demonstrators at the border.
