The UN's humanitarian chief, Tom Fletcher, has welcomed Israel's measures to allow more aid into Gaza, but said "vast amounts" of food are needed to stave off starvation.
Israel said 120 lorry loads were collected from crossings on Sunday during the first daily 10-hour "tactical pause" in military operations, and that Jordan and the United Arab Emirates airdropped 28 packages of food.
However, Fletcher told the BBC that it was just "a drop in the ocean" of what was required and that the coming days would be "make or break".
Hours after he spoke, the territory's Hamas-run health ministry said another 14 people had died as a result of malnutrition over the past 24 hours.
That brought the total number of malnutrition-related deaths since the war begin in October 2023 to 147, including 88 children, according to the ministry.
