Yemen's coast guard said the dead included four crew members and two members of the government-allied National Resistance Forces. Houthis fired three ballistic missiles at the Yemeni commercial vessel, according to the Transportation Ministry of Yemen's internationally recognized government. They are the first known deaths from Houthi attacks on shipping off Yemen in the latest bout of fighting in the Arab country. The US military said Tuesday that its forces fired on a Panamanian-flagged ship in the Gulf of Oman that tried to evade the American blockade on Iranian ports. Central Command said it has redirected 55 commercial vessels attempting to run the blockade, disabled three non-compliant vessels and boarded two.
