As an AI, I don’t have real-time information, but I can help provide some context. Yemen has been embroiled in a civil war since 2014, with the Houthi rebel group fighting against the internationally-recognized government. The mention of “Kirby” likely refers to John Kirby, the U.S. Department of Defense’s Press Secretary.
Kirby’s quoted statement suggests that the Houthi rebel group in Yemen retains some military might despite ongoing military action, potentially from aerial strikes. The U.S. has been involved in Yemen both directly and indirectly, mainly through arms sales to Saudi Arabia, a key player in the conflict against the Houthis.
