LIVE | Day 32: Netanyahu says Israel will have ''overall security responsibility'' in Gaza after war

Bombardment in North Gaza

Several hundred thousand people are believed to remain in the north in the path of the assault of the Israeli military. The military says a one-way corridor for residents of Gaza City and surrounding areas to flee south remains available. But many are afraid to use the route, part of which is held by Israeli troops.

In recent days, airstrikes have hit UN facilities where thousands are sheltering, as well as hospitals, which have been overwhelmed by wounded and running low on power and supplies.

A strike early on Monday hit the roof of Gaza City's Shifa Hospital, killing a number of displaced people sheltering on its top floor and destroying solar panels, said Mohamed Zaqout, general manager of all hospitals in Gaza. The panels have been helping keep power on in the facility, which has been reduced to using one generator because of lack of fuel. The strike came in what witnesses said was one of the heaviest nights of bombardment yet in northern Gaza.

Israel said it struck 450 targets overnight, killing a number of Hamas military commanders. Israel blames civilian casualties on Hamas, accusing the militants of operating in residential neighborhoods. The overnight barrages crushed homes, burying unknown numbers of people underneath, in the Shati refugee camp, a densely built-up district on the Mediterranean coast adjacent to central Gaza City, Palestinians who fled south Monday reported.
