Sunday became the deadliest day in the week of Israeli-Palestinian fighting so far, with Israel striking residences in Gaza City and Hamas firing more than 100 rockets across the border. The Israeli airstrikes targeted several homes on a main road leading to Shifa Hospital, the Washington Post reports. Gaza's Health Ministry said at least 42 people were killed, 10 of them children, and people were still searching the rubble. The Israeli military said it destroyed the homes of Hamas leader Yehiya Sinwar, his brother, and several commanders. Hamas had continuously launched rockets at cities and towns in southern Israel, as well as Tel Aviv, on Saturday. An Israeli general said more rockets were fired at Tel Aviv on Saturday night than it had endured in all of the 2014 war. The official death toll in Gaza has reached 188, including at least 55 children, per CNN.
