In a statement signed by 111 organizations, including Mercy Corps and Refugees International, the groups warned that mass starvation was spreading.

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.

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

The joint statement comes as Palestinians face worsening starvation, daily massacres at "aid sites" and the ongoing blockade of humanitarian assistance.

The Norwegian Refugee Council, one of the largest independent aid organisations in Gaza, told Reuters on Tuesday its supplies were exhausted and some of its staff starving, and the group accused Israel of paralysing its work.

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.

Ciarán Donnelly, who oversees the International Rescue Committee’s work in Gaza, explains how “insufficient” and “dehumanizing” the aid crisis is for residents. He tells CNN’s Brianna Keilar about the challenges they face by not having permission to share supplies with civilians who desperately need it.

In a joint statement the countries call for an end to the war and the release of Israeli hostages held in Gaza.
