Israel has banned the operations of the medical charity Doctors Without Borders (MSF) in Gaza and ordered the organization to leave the enclave by February 28, according to TRT World. Israeli authorities said the decision followed MSF’s refusal to submit a list of its staff to Tel Aviv, a requirement applied to all humanitarian organizations operating in the region.

Citing the newspaper Maariv, Israel stated that the measure aims to ensure legitimate relief activities and prevent the misuse of humanitarian aid for terrorism. MSF responded that it would not provide the names of its Palestinian and international staff because Israel had refused to guarantee their safety or the organization’s operational independence.

MSF is one of the largest humanitarian organizations working in Gaza. Observers fear that halting its activities could severely threaten medical services in the territory, already devastated by two years of war that have killed about 71,800 Palestinians, injured more than 171,400, and destroyed nearly 90 percent of civilian infrastructure.
