The Israeli military has intercepted a Gaza-bound aid ship, detaining 21 international activists and journalists and seizing all cargo, including baby formula, food, and medicine, according to the Freedom Flotilla Coalition.

Israel said it resumed aid airdrops to Gaza on Saturday and was taking several other steps to ease the humanitarian crisis in the Palestinian enclave, amid mounting international pressure and warnings from relief agencies of starvation spreading there.

As starvation rises in Gaza, prompting global outrage, Israel’s military said it would restart airborne aid delivery there and make land deliveries less dangerous.
