Mike Waltz said the strike targeted the Houthis' 'top missile guy' when he entered a building where his girlfriend lived

The full Signal chat between Trump administration officials discussing bombing Yemen revealed that top US officials celebrated an airstrike that flattened a residential building, which likely killed many civilians.

Jeffrey Goldberg, editor-in-chief of The Atlantic, was included in the chat, apparently by accident, and published its full contents on Wednesday after Trump administration officials insisted it didn't contain classified information. But the chat did include details about when the strikes on Yemen would start on March 15.

After the US bombings started, US National Security Advisor Mike Waltz, who added Goldberg to the chat, said one of the strikes targeted a "top missile guy" for the Houthis after he entered a building where his girlfriend lived.
