A ban on UNRWA would lead to the collapse of humanitarian aid operations at large in Gaza, aid groups have warned.

The Israeli Foreign Ministry said in a statement that it had notified the U.N. of the cancellation of an agreement dating back to 1967 that facilitates UNRWA's work.

Many Palestinians see darker motives, viewing the UNRWA ban as Israel's latest attempt to make their lives unlivable, first imprisoning and bombing them, now taking away their main aid lifeline. “The impact on the ground will be horrible,” Mustafa Barghouti, head of the Palestinian National Initiative political party, told NBC News.
