Iran and Qatar resume maritime trade: Iranian state media Maritime trade between Iran and Qatar has resumed after a roughly five-month suspension, Iran's commercial attache in Doha told state media on Sunday. An interim deal between Tehran and Washington signed last month announced the end of hostilities after a four-month conflict, and mandated a return to pre-war maritime traffic in the Gulf, although transit in and out of the Gulf remains contested. Abbas Abdolkhani said shipping between Iran's Dayyer port and Qatar's Al-Ruwais port had resumed following coordination between the Iranian embassy in Doha and Qatari authorities.
