A ban preventing UNRWA, the UN Agency for Palestinian Refugees, from operating in Occupied East Jerusalem and Israel has come into force today. The ban only concerns operations in Occupied East Jerusalem, but Israel has also severed communication with the Agency and revoked the visas of international staff, making it extremely hard to continue services in Gaza and the West Bank. UNRWA provides medical services to at least 70,000 Palestinians in Jerusalem and runs schools for thousands of pupils as well as maintaining streets and carrying out waste disposal. The collapse of UNRWA in the West Bank and Gaza Strip is concerning and will have devastating consequences on food security.
