Israeli air strikes killed 33 Palestinians, including 13 children, in Gaza early on Sunday, Gaza health officials said as hostilities stretched into a seventh day.
The pre-dawn attacks were on houses in the centre of Gaza City, health officials said.
The death toll in Gaza jumped to 181, including 52 children, since the fighting erupted last Monday.
With no sign of an end to the worst outbreak of violence in years, the United Nations Security Council was due to meet later on Sunday to discuss the situation.
Israel destroyed a 12-storey building in Gaza City on Saturday that housed the U.S. Associated Press and Qatar-based Al Jazeera media operations.
The Israel military said the al-Jala building was a legitimate military target, containing Hamas military offices, and that it had given advance warnings to civilians to get out of the building.
The AP condemned the attack, and asked Israel to put forward evidence. "We have had no indication Hamas was in the building or active in the building," it said in a statement.
Palestinians working to clear rubble from a building wrecked in Sunday's air strikes recovered the bodies of a woman and man.
"These are moments of horror that no one can describe. Like an earthquake hit the area," said Mahmoud Hmaid, a father of seven who was helping with the rescue efforts.
