At 8.30 on Friday morning, Jenin’s morgue was crowded. Outside, dozens of young men in black baseball caps, T-shirts and jeans stood quietly, some with their weapons between their knees, their green Hamas headbands tied tight across their foreheads. Older men sat in front of shuttered shops.

Inside, a metal door was opened and a corpse wrapped in the green flag of Hamas was drawn out on a stretcher. A teenager with an assault rifle in one hand touched the dead man lightly on the forehead, then helped to shoulder the stretcher and with five others set out through the throng, down the rubble-strewn streets to the home of Hamed Fayed, where the women of the family waited.

Monitoring group says increased fatality average in latest Gaza air campaign may indicate shift in strategy

Each recorded fatal Israeli airstrike on Gaza since 7 October has caused an average of 10.1 civilian deaths, a monitoring group has said, amid warnings that reported civilian casualty figures are likely to be an underestimate.

The fatality average is far higher than in the three previous Israeli air campaigns in Gaza, of which the most deadly was Operation Protective Edge in the summer of 2014, where the equivalent figure was 2.5.
