The strike was conducted by the USS Carney using Tomahawk Land Attack missiles, U.S. Central Command said in a statement released later Friday.

The strikes were separate from the previous strikes conducted under Operation Prosperity Guardian, a defensive coalition of over 20 countries operating in the Red Sea, Bab al-Mandeb Strait and Gulf of Aden, the statement said.

The decision will please critics of the Biden administration who argue the U.S. should use more force on the Houthis to send a message, but it will anger congressional Democrats and Republicans who believe the president required their approval before greenlighting the operation.

Biden on Friday formally notified Congress of the air and missile strikes, writing in a letter that they “were taken to deter and degrade Houthi capacity to conduct future attacks.”
