The Israeli military appears to have encircled Gaza City, but so far, it's made only limited forays into the densest urban areas.

Israel's military said that it would continue to allow Gazans to evacuate south as hundreds of thousands had already moved. Israeli strikes on the Gaza Strip have killed more than 2,600 Palestinians.

A dozen journalists and freelancers were evacuated from the AP offices in the 12-story building before it crumbled to the ground. AP said the military has long known the building housed journalists.
