After mounting international pressure, the Israeli military announced on Sunday that it will take a series of actions to improve the humanitarian response in Gaza. While some aid has trickled in, it's nowhere near enough. The UN says more food is needed to prevent famine and a catastrophic health crisis.

Tom Fletcher is the United Nations Under-Secretary-General for Humanitarian Affairs and Emergency Relief Coordinator (OCHA). He welcomes Israel’s “humanitarian pauses” in Gaza, but warns real aid requires open crossings and fewer restrictions.
