World Central Kitchen (WCK) founder José Andrés has accused Israeli forces in Gaza of targeting his aid workers “systematically, car by car”.
Monday’s strike which killed seven members of his staff was not a mistake, he said, repeating that Israeli forces had been told of their movements.
WCK workers from Australia, Canada, Poland, the UK and the US were killed as well as their Palestinian colleague.
Israel says the strike was a “grave mistake” and has apologised.
It has also promised an independent investigation.
According to the charity, the aid convoy was hit while leaving the Deir al-Balah warehouse, “where the team had unloaded more than 100 tonnes of humanitarian food aid brought to Gaza on the maritime route”.
The convoy was made up of three vehicles, including two that were armoured, which clearly displayed the charity’s logo. All three were hit during the strike.
