Palestinian health officials and witnesses say Israeli forces fired toward crowds making their way to a food distribution point run by an Israeli and U.S.

When university professor Nizam Salama made his way to a southern Gaza aid point last week, he came under fire twice, was crushed in a desperate crowd of hungry people and finally left empty handed.

Witnesses say the gunmen shot at them while organising queues for food near a site run by an Israeli- and US-backed group.
