A new program for getting desperately needed food into the hands of starving Palestinians in Gaza is only days old, but it’s already mired in chaos and tragedy.

The U.N. Security Council is set to vote on Wednesday on a demand for a ceasefire between Israel and Hamas and humanitarian access across Gaza, where malnutrition is widespread and aid has only trickled in since Israel lifted an 11-week blockade in late May.

The U.S backed-Gaza Humanitarian Foundation said on Friday that all its aid distribution sites in the enclave were closed and a reopening date would be announced later, urging residents to stay away from these sites "for their safety".
