Investigation based on visual evidence, bullets, medical records and testimony appears to show sustained pattern of Israeli shootings

Warning: includes images of blood and graphic scenes

Ehab Nuor, a 23-year-old barber, lies flat on the sand behind entangled metal, hiding from heavy machine-gun fire, as hundreds of Palestinians scramble away, carrying backpacks in which they had hoped to collect food.

Nuor has come under fire from the Israeli military near food distribution centres on more than 10 occasions.

A Guardian investigation analysing visual evidence, bullets, medical data and patterns of injuries from two hospitals, as well as interviews with medical organisations and surgeons, across approximately 50 days of food distribution, appears to show a sustained Israeli pattern of firing on Palestinians seeking food.
