Israel’s military chief says the deadly Israeli strike was the result of a “misidentification” in complex conditions.

Announcing the results of a preliminary investigation early Wednesday, Lt. Gen. Herzi Halevi expressed remorse over the killings and called the event a “grave mistake.”

“It was a mistake that followed a misidentification – at night during a war in very complex conditions. It shouldn’t have happened,” he said. He gave no further details.

He said an independent body would conduct a “thorough investigation” that would be completed in the coming days, and said the army appreciates the “important work” of the World Central Kitchen.

He said the conclusions of the independent investigation would be implemented immediately and shared with World Central Kitchen and other “relevant” international organizations.

“We see great importance in the continued delivery of humanitarian aid, and we will keep working to facilitate this vital effort,” he said.

World Central Kitchen said it had coordinated with the Israeli military over the movement of its cars. Three vehicles that were moving at large distances apart were hit in succession. They were left incinerated and mangled, indicating multiple targeted strikes.

At least one of the vehicles had the charity’s logo printed across its roof to make it identifiable from the air, and the ordnance punched a large hole through the roof.

The strikes on the charity’s convoy highlighted what critics say is Israel’s indiscriminate bombing and lack of regard for civilian casualties in Gaza. Israeli authorities blame Hamas militants for civilian deaths because the fighters operate in populated areas.
