The U.N. says it is trying to get the desperately needed aid that has entered Gaza this week into the hands of Palestinians.

One aid group said the “ridiculously inadequate amount of aid” Israel was allowing into Gaza was simply “a smokescreen to pretend the siege is over.”

Palestinians in Gaza were left waiting for the promised arrival of food on Wednesday despite mounting international and domestic pressure on the Israeli government to allow more aid to reach a population on the brink of famine after an 11-week blockade.
