Three vehicles were hit, at least one of which had the WCK logo printed across its roof. The vehicle was left with a huge hole in the roof following the attack.
Israeli security forces have told Haaretz that they had followed the vehicle and had reason to believe a Hamas operative was traveling with the vehicles.
Israel’s Prime Minister Benjamin Netanyahu has addressed the strike, branding it “unintended” and promising aid workers will not be killed again.
Gaza’s humanitarian crisis could also worsen as ships carrying 240 tonnes of food aid have been told to turn around after the bombing.
US President Joe Biden has said Israel is not doing enough to protect aid workers while British Prime Minister Rishi Sunak has said he is “appalled”.
Sunak added: “We’re asking Israel to investigate what happened urgently, because clearly there are questions that need to be answered.”
