Gaza health officials and the ambulance service say at least 25 people were killed by Israeli airstrikes and gunshots overnight as ceasefire talks appear to have stalled and Palestinians in Gaza are facing famine.

Médecins Sans Frontières (MSF) says the air drops "might help" but notes that the "most vulnerable" in Gaza would still struggle to access essential supplies.

A joint statement called for an immediate ceasefire and said that "withholding essential humanitarian assistance to the civilian population is unacceptable."

Israel’s military took journalists on Thursday to the Gaza side of the Kerem Shalom crossing to show what they claim is humanitarian aid awaiting collection.

Prime Minister Mark Carney is calling for Israel’s control of aid distribution to be replaced amid reports of mass starvation in Gaza.

Israel denies that it is responsible for hunger in Gaza. It called the countries’ statement “disconnected from reality” and blamed Hamas for undermining aid distribution and failing to agree to a ceasefire.

Only a few weeks ago, President Donald Trump seemed confident a deal was days away that would end the fighting in Gaza, secure the release of hostages and allow aid to flow into an enclave where people are starving to death.

Gaza ceasefire talks are expected to resume next week following Israel's review of the response by Palestinian Hamas militants, Egyptian state-affiliated Al Qahera News TV said on Friday, citing an Egyptian source.
