An Israeli strike on the Jabaliya refugee camp in northern Gaza on Sunday killed 90 Palestinians, the Hamas-run health ministry has claimed.
The strikes hit a residential block housing two families, the health ministry said.
There was no immediate response from the Israeli Defense Force (IDF).
Israeli forces launched deadly attacks up and down the Gaza Strip on Sunday amid growing international pressure for a ceasefire.
Around 19,000 Palestinians have been killed since the beginning of the war, according to Gaza health officials.
It comes as Ben Wallace, the former Defence Secretary, warned Israel risks losing legal authority for its war in Gaza by going on a crude and indiscriminate “killing rage” against the Palestinian people.
