Iranian forces seized a U.S. cargo vessel, Saudi-owned Arabiya television reported, without saying where it obtained the information.
Iranian forces took the vessel to the Persian Gulf port of Bandar Abbas, the Dubai-based television station said. The vessel carried at least 24 people on board, it said. The Iranians opened fire at the vessel before escorting it, Arabiya said.
There was no immediate comment from U.S. or Iranian authorities on the report.
Tensions between Iran and Saudi Arabia have escalated as the kingdom carried out airstrikes against Shiite rebels in Yemen. Iran has also chided the U.S. for siding with the Saudis against the Houthi rebels. Still, ties between Iran and the U.S. have improved in the past two years amid progress in talks on an accord to rein in the Islamic Republic’s nuclear program and ease sanctions on its economy.
