Two basic mistakes, according to the Israeli military. First, an officer overlooked a message detailing the vehicles in the convoy. Second, a spotter saw something in one car – possibly a bag – that he thought was a weapon. Officials say the result was the series of Israeli drone strikes that killed seven aid workers on a dark Gaza road.

The Israeli military has described the deadly strike on the World Central Kitchen convoy as a tragic error. Its explanation raises the question: If that’s the case, how often has Israel made such mistakes in its 6-month-old offensive in Gaza?

Rights groups and aid workers say Monday night’s mistake was hardly an anomaly. They say the wider problem is not violations of the military’s rules of engagement but the rules themselves.

In Israel’s drive to destroy Hamas after its Oct. 7 attacks, the rights groups and aid workers say, the military seems to have given itself wide leeway to determine what is a target and how many civilian deaths it allows as “collateral damage.”
