At least four people died in Gaza as hundreds of aid-starved Palestinians broke into a United Nations food warehouse yesterday in a desperate attempt to get something to eat.

Two people were crushed to death as the heaving mass of humanity poured into the Al-Ghafari warehouse housing supplies provided by the UN's World Food Programme (WFP), while two others were reportedly shot dead.

Heartbreaking footage of the crush showed frenzied Gazans tearing pieces off the building located in Deir Al-Balah in an attempt to get at the supplies inside.

Gunshots were clearly heard ringing out in the clip, though it is not clear who fired on the group.

The humanitarian situation in Gaza, where aid has finally begun to trickle in after a two-month blockade, is dire following more than 18 months of devastating war.
