President Biden said he was “outraged and heartbroken” over the deaths, but at a White House press briefing, National Security Council spokesperson John Kirby refused to say if Israel had broken international law.

Niall Stanage: “Is firing a missile at people delivering food and killing them not a violation of international humanitarian law?”

John Kirby: “Well, the Israelis have already admitted that this was a mistake that they made. They’re doing an investigation. They’ll get to the bottom of this. Let’s not get ahead of that. … The State Department has a process in place. And to date, as you and I are speaking, they have not found any incidents where the Israelis have violated international humanitarian law.”

On Tuesday, World Central Kitchen and at least two other groups said they would halt or pause operations in Gaza after the attack. A World Central Kitchen boat that still held 240 tons of aid on board left Gaza on Tuesday.
