Israeli forces battled Hamas-led fighters in several parts of the Gaza Strip on Tuesday, and Palestinian health officials said at least 57 people were killed in Israeli bombardments of southern and central areas.
The Palestinian Islamist militant group Hamas has accused Israel of stepping up attacks in Gaza to try to derail efforts by Arab mediators and the United States to reach a ceasefire deal. Israel says it is trying to root out Hamas fighters.
In Rafah, a southern border city where Israeli forces have been operating since May, five Palestinians were killed in an airstrike on a house, Gaza health officials said. In nearby Khan Younis, a man, his wife, and two children were killed, they said.
