A U.S. military campaign of strikes in Yemen launched just over a week ago has so far taken out key Houthi leadership, including the group's top missile specialist, White House National Security Adviser Mike Waltz said on Sunday. "We've hit their headquarters, we've hit communications nodes, weapons factories, and even some of their over-the-water drone production facilities," Waltz told CBS News. He did not identify the slain missile specialist and gave no details on the other leaders who have been killed.
