Israeli Prime Minister Benjamin Netanyahu has vowed to step up attacks on the Gaza Strip after a weekend of violence that left hundreds of Palestinians dead. On Friday, 90 people were killed when Israel bombed two homes in Gaza City. Seventy-six of the dead were members of one family. They include Issam al-Mughrabi, who worked as a United Nations Development Program official for three decades. He was killed along with his wife and five of their children. On Sunday, at least 106 Palestinians were killed in a single Israeli airstrike on the Maghazi refugee camp in Gaza. This is Ibrahim Youssef, a camp resident who searched for his wife and four children after the attack buried them under the rubble.
