The US Defence Secretary, Pete Hegseth, sent messages about US air strikes in Yemen to a private group on the Signal app. He shared flight times for American planes with his wife, brother, and lawyer in the group. The White House said he did not share secret information.

Some people are worried because his wife does not work for the government. His brother and lawyer work at the Department of Defense, but it is not clear why they needed this information. Experts say it is safer to talk about military plans in special government places, not on private phones.

The US says it attacks the Houthis in Yemen because they attack ships in the Red Sea. Many people died in a recent US air strike in Yemen. Some people say these attacks are a war crime. There is a lot of disagreement about what happened.
