European Union foreign affairs chief Josep Borrell said this week that “starvation is being used as a war arm” in Gaza, calling the humanitarian crisis “man-made”, AFP reports.

Daily aid airdrops by multiple countries have been taking place this month, but they are “no alternative” to land deliveries, 25 organisations including Amnesty International and Oxfam said in a statement.

Despite airdrops being far from sufficient to address the scale of the humanitarian disaster, the international community is doing what it can, said the US serviceman.

“Anything outside of air dropping is out of our control, so we’ll manage the things that are within our control,” said Anderson.

The dire shortages have left starving Palestinians scrambling for scraps of aid, sometimes at a deadly cost.
