Suspected U.S. airstrikes in Yemen's Houthi stronghold of Saada have killed at least two people and wounded four others, according to the group. The airstrikes come as a video posted by U.S. President Donald Trump suggests that casualties in the campaign may be higher than the rebels acknowledge. The intense campaign of airstrikes in Yemen, targeting the rebels over their attacks on shipping in Mideast waters, has killed at least 69 people, according to the Houthis. The U.S. military's Central Command has not released specific details about the strikes it has conducted since March 15.
