WASHINGTON (Reuters) - The U.S. military is carrying out an additional strike against the Houthis in Yemen, a day after launching a wave of attacks on nearly 30 locations in the country to degrade the Houthis' ability to strike Red Sea shipping, two U.S. officials told Reuters on Friday.

       The officials, who spoke on condition of anonymity, declined to provide further details.
