DEIR AL-BALAH, Gaza Strip (AP) — Civil defense workers in Gaza have been digging bodies out of collapsed buildings and pulling them off rubble-covered streets. The effort unfolded Friday as they collected dozens of Palestinians killed this week by an Israeli assault in a district of Gaza City. The discovery of the bodies came after Israeli troops reportedly pulled out of parts of the Tal al-Hawa and Sinaah neighborhoods following days of bombardment and fighting. The Israeli military launched an incursion into the districts earlier this week to fight what it said were Hamas militants who had regrouped. The grisly scenes of the dead underscored the horrifying cycle nine months into the Gaza war.
