UN-backed experts say there have been improvements in nutrition and food supplies in Gaza since the ceasefire, but 100,000 people still experienced "catastrophic conditions" last month.

In August, the Integrated Food Security Phase Classification (IPC) which monitors and classifies global hunger crises said that half a million people - about a quarter of Gaza's population - lived in areas suffering from famine.

The UN and other humanitarian agencies have been able to increase food getting into Gaza since October's ceasefire between Israel and Hamas.

Israel's foreign ministry said the IPC report was "deliberately distorted" and "doesn't reflect the reality in the Gaza Strip".

The latest IPC analysis suggests that a month ago, half a million Gazans were still facing emergency conditions and more than 100,000 were still under the highest level of food insecurity - IPC Phase 5 - experiencing "catastrophic conditions".

It projects that number will continue to decrease but stressed the situation remains "highly fragile".

IPC Phase 5 signifies the most extreme level of food insecurity, labelled "famine" for an area or "catastrophe" when referring to households. The report said no areas in Gaza were now classified as "in famine".

Israel rejected the original findings of famine by the IPC and has continued to criticise its methodology.

Cogat, the Israeli military body which controls Gaza's crossings, said the number of trucks with food aid entering each week went beyond what the UN had determined it needed.

"The report relies on severe gaps in data collection and on sources that do not reflect the full scope of humanitarian assistance," the body said in a statement.

Responding to the Cogat ctiticism, the IPC said publicly available data from UN sources and Cogat had been used for the analysis.

The IPC said acute malnutrition was at critical levels in Gaza City and serious in Deir al-Balah and Khan Younis.

In the coming months the situation is expected to remain severe but the number of people facing the most severe conditions is predicted to fall to 1,900 by April, according to the report.

But it added that, if there were renewed hostilities, the entire Strip would be at risk of famine.

Israel's Prime Minister Benjamin Netanyahu said earlier this month that the second phase of the US-brokered peace plan - which would see Israel withdraw troops further from Gaza and Hamas disarm - was close but key issues still needed to be resolved.

The IPC said key drivers of food insecurity included restricted humanitarian access, displacement of more than 730,000 people and the destruction of livelihoods - including more than 96% of crop land in Gaza being destroyed or inaccessible.

Israel imposed a total blockade on aid deliveries to Gaza at the start of March this year, which was eased in May, saying it wanted to put pressure on the armed group Hamas to release hostages remaining in Gaza at the time.

Ahead of this IPC report, Cogat said the body had not engaged with the US or Israel and its methodology, "reinforcing a false narrative, driven in part by Hamas-sourced claims".

It also denied Israel was preventing winter and medical supplies from entering the territory and that there was a shortage of drinking water.

Unwra, the UN agency for Palestinian refugees, said that while, the report stated Gaza was no longer in famine, the situation remained "critical".

"Overall living conditions in the Gaza Strip are still catastrophic, made worse by the winter weather," it said in a statement, adding there must be "sustained, expanded, and consistent humanitarian and commercial access".
