Sunday became the third and deadliest day for the Gaza Strip as both sides reported a record number of deaths, the New York Times wrote. More than 100 Palestinians died Sunday, and Israel’s military said that 13 of its soldiers were killed. Since the fighting started on July 8, the death total in Gaza has soared to at least 570 dead and more than 3,350 thousand have been wounded, according to CBS News.

The United States pledged $47 million in humanitarian aid as tens of thousands of Palestinians have been forced to leave their home in the Gaza Strip. Fighting between Israel and the militant group Hamas, which controls Gaza, has moved into its third week.
