For months, the U.N. and experts have warned that Palestinians in Gaza are at risk of famine, with reports of increasing numbers of people dying from causes related to malnutrition.

Israel has restarted airdrop aid to Gaza, aiming to alleviate a looming mass starvation identified by over 100 aid agencies. Humanitarian corridors and pauses will be established to assist UN convoys.

More than 100 charity and human rights groups say Israel’s blockade and ongoing military offensive are pushing Palestinians in the Gaza Strip toward starvation. Israeli strikes meanwhile killed another 21 people overnight and into Wednesday, according to local health officials.
