The Health Ministry in Hamas-run Gaza said the death toll has surpassed 15,200 and that 70 per cent of those killed were women and children.
The figure was announced on Saturday by ministry spokesman Ashraf al-Qidra, who did provide further details.
The previous toll given by the ministry was more than 13,300 dead. Al-Qidra did not explain the sharp jump. However, the ministry had only been able to provide sporadic updates since November 11, amid problems with connectivity and major war-related disruptions in hospital operations.
The ministry does not differentiate between civilians and combatants.
Some 2 million people - almost Gaza's entire population - are crammed into the territory's south, where Israel urged people to relocate at the war's start and has since vowed to extend its ground assault. Unable to go into north Gaza or neighbouring Egypt, their only escape is to move around within the 220-square-kilometre (85-square-mile) area.
In response to US calls to protect civilians, the Israeli military released an online map, but it has done more to confuse than to help.
It divides the Gaza Strip into hundreds of numbered, haphazardly drawn parcels, sometimes across roads or blocks, and asks residents to learn the number of their location in case of an eventual evacuation.

The publication does not specify where people should evacuate to, the UN office for coordinating humanitarian issues in the Palestinian territory noted in its daily report. It is unclear how those residing in Gaza would access the map without electricity and amid recurrent telecommunications cuts.
Egypt has expressed concerns the renewed offensive could cause Palestinians to try and cross into its territory. In a statement late Friday, the Egyptian Foreign Ministry said the forced transfer of Palestinians is a red line".
US Vice President Kamala Harris, who was in Dubai on Saturday for the COP28 climate conference, was expected to outline proposals with regional leaders to put Palestinian voices at the centre of planning the next steps for the Gaza Strip after the conflict, according to the White House. US President Joe Biden's administration has been emphasising the need for an eventual two-state solution, with Israel and a Palestinian state coexisting.
The renewed hostilities have also heightened concerns for 136 hostages who, according to the Israeli military, are still held captive by Hamas and other militants after 105 were freed during the truce.
For families of remaining hostages, the truce's collapse was a blow to hopes their loved ones could be the next out after days of seeing others freed. The Israeli army said Friday it had confirmed the deaths of four more hostages, bringing the total known dead to seven.
During the truce, Israel freed 240 Palestinians from its prisons. Most of those released from both sides were women and children.
The war began after the Oct 7 attack by Hamas and other militants, who killed about 1,200 people, mostly civilians, in southern Israel and took around 240 people captive.
After the end of the truce, militants in Gaza resumed firing rockets into Israel, and fighting broke out between Israel and Hezbollah militants operating along its northern border with Lebanon.
