Iman Helles, a displaced mother sheltering in a facility run by the UN agency for Palestinian refugees in Gaza, fears that she will now be “thrown out to the streets” with her three children.

Legislation that goes into effect on Thursday bars UNRWA from operating in the country. That will affect aid delivery to Gaza and beyond.

The U.N. Palestinian relief agency said its humanitarian work across the occupied territories and Gaza was still ongoing on Friday despite an Israeli ban that took effect a day before and what it described as hostility towards its staff.
