The health ministry in Gaza said Sunday at least 25,105 people have been killed in the Palestinian territory since October 7.
A ministry statement said some 62,681 people were also wounded in the attacks by Israeli forces.
Fighting raged across Gaza and Israeli units raided the West Bank on Sunday after Prime Minister Benjamin Netanyahu, who has faced growing domestic criticism, rejected calls for post-war "Palestinian sovereignty".
Alongside fierce fighting in southern Gaza and across the besieged territory, strikes in Syria and Iraq raised fears of a wider conflagration.
Gaza's health ministry reported at least 165 people killed over the previous 24 hours -- more than double Friday's toll.
In Rafah, near the border with Egypt, at least five people were killed in a strike that hit what the Gaza health ministry said was a civilian car.
The UN agency for Palestinian refugees UNRWA says about 1.7 million people have been displaced in Gaza, with about one million crowded into the Rafah area. The UN humanitarian agency OCHA reported just 15 bakeries operating across Gaza and that the availability of water "is shrinking every day".
UN agencies have warned better aid access is needed urgently as famine and disease loom.
