More than 40 Palestinians have been killed in the Gaza city of Rafah following the collapse of a U.S.- and U.N.-backed ceasefire. Reuters reports Israeli tanks opened fire in the southern Rafah area just hours after the 72-hour ceasefire began. Israel is claiming Hamas first broke the ceasefire by firing rockets at Israeli forces. The Israeli military has launched a major effort to locate a soldier they fear was captured near Rafah. The Palestinian death toll from Israel’s offensive in Gaza has now reached at least 1,460, mostly civilians. The toll surpasses the number of Palestinians killed during Israel’s Operation Cast Lead nearly six years ago. Sixty-four Israeli soldiers have been killed, in addition to three civilians.
