Thousands of people broke into aid warehouses in Gaza to take flour and basic hygiene products, signaling growing desperation and the breakdown of public order. Israeli Prime Minister Benjamin Netanyahu announced a “second stage” in the war against Gaza’s militant Hamas rulers as tanks and infantry pushed into Gaza over the weekend. The Israeli military said it had struck over 450 militant targets in the past 24 hours. UNRWA, the U.N. agency for Palestinian refugees, said the warehouse break-ins were a sign that civil order is breaking down. Israel has allowed only a small trickle of aid to enter from Egypt.
