Seven aid workers who had just delivered more than 100 tons of food to central Gaza were killed last night by Israeli strikes. The workers were driving in a clearly marked aid convoy, and they had coordinated their movements with Israeli officials. Prime Minister Benjamin Netanyahu apologized and said Israel “deeply regrets the tragic incident.”

Videos and photos verified by The New York Times suggest the convoy was hit multiple times. The imagery shows three destroyed white vehicles, with the northernmost and southernmost vehicles nearly a mile and a half apart.

“There was a tragic case of our forces unintentionally hitting innocent people in the Gaza Strip,” Netanyahu said. “We will do everything so that this thing does not happen again.”

Aid organizations and several governments condemned the attack. The workers — a Palestinian, an Australian, a Pole, three Britons and a dual U.S.-Canadian citizen — were with the charity group World Central Kitchen, a newly important player in the effort to alleviate a looming famine in Gaza.

The incident underscored the risks to humanitarian workers in the area. At least 196 have been killed in Gaza and the West Bank since October, a senior U.N. official said. World Central Kitchen said it was suspending its operations in Gaza.
