Patients crowded into wards at a Gaza hospital fear they could be left without care after Israel announced it will bar 37 aid organizations, including Doctors Without Borders, from operating in the territory from March 1 over staffing disclosure requirements.

"They stood by us throughout the war," said 10-year-old Adam Asfour, his left arm pinned with metal rods after he was wounded by shrapnel in a bombing in September.

"When I heard it was possible they would stop providing services, it made me very sad," he added from his bed at Gaza's Nasser Hospital.

Israel's Ministry of Diaspora Affairs and Combating Antisemitism, which oversees NGO registrations, has accused two MSF employees of links to Palestinian resistance groups Hamas and Islamic Jihad, allegations MSF vehemently denies.

The ministry's decision triggered international condemnation, with aid groups warning it would severely disrupt food and medical supplies to Gaza, where relief items are already scarce after more than two years of genocidal war.
