US says several Houthi leaders killed in attacks, with Iran shown ‘enough is enough’

US strikes killed a number of Houthi leaders in Yemen, the White House said on Sunday. Iran has been “put on notice” to stop backing the rebel group and its attacks on Red Sea shipping, Washington added. The military strikes on Saturday “actually targeted multiple Houthi leaders and took them out”, National Security Adviser Michael Waltz told ABC News. “We just hit them with overwhelming force and put Iran on notice that enough is enough,” he said in a separate appearance on Fox News.
