Dozens of international humanitarian organizations warned Israel’s blockade of aid into Gaza is endangering the lives of doctors and aid workers, while a major news agency says it is trying to evacuate its remaining freelance journalists because the situation has become “untenable.

WASHINGTON (Reuters) -U.S. President Donald Trump's Middle East envoy Steve Witkoff will travel to Europe this week for meetings on Israel's war in Gaza and a range of other issues, a U.S. official said on Tuesday, adding Witkoff will continue pushing for a ceasefire in the Palestinian enclave.

The humanitarian crisis in Gaza is escalating, with health officials warning that 15 people, including four children, have died due to malnutrition in just the last 24 hours. NBC News’ Matt Bradley reports as international pressure mounts on Israel to allow more aid into the region.

U.N. officials, aid groups and experts have warned for months that Palestinians in Gaza are on the brink of famine without formally declaring one.

As Israel faces mounting pressure to end the Gaza war, a hospital director says the Palestinian enclave is facing "alarming numbers of deaths" from starvation.

The evacuation order has cut off the coastal area of Al Mawasi, where thousands of Palestinians are living in tents, from the city to the rest of central Gaza, where most humanitarian organizations in the Strip are headquartered, according to a visual analysis by ABC News.

The Gaza Humanitarian Foundation is challenging the U.N.'s claims about restrictions on aid distribution in the Strip as the U.S.- and Israel-backed organization delivers over 85 million meals in under two months.

The aid agency says its buildings in the central part of the territory were attacked after the military targeted Deir al-Balah, which had largely been spared.

A group of journalists at the Agence France-Presse news agency is sounding the alarm about conditions faced by colleagues working in Gaza, saying that “without immediate intervention, the last reporters in Gaza will die.

New figures from the Hamas-run ministry include 12 children who have died, as the UN says Israel must allow aid into Gaza.

LONDON -- The World Health Organization said it will expand its medical services in Gaza, even after its staff residence in Deir al Balah, Gaza, was attacked three times by the Israel Defense Forces, WHO officials said Tuesday.
