Details are still coming in, but it seems clear that the Iranian Navy seized a container ship called the Maersk Tigris that was transiting the Strait of Hormuz this morning. The ship, flagged in the Marshall Islands and owned by a Danish conglomerate, was traveling on an internationally recognized shipping route when it was approached by Iranian vessels that ordered it to “proceed further” into Iranian waters. The captain refused, and the Iranian vessels fired warning shots. The captain then “complied with the Iranian demand and proceeded into Iranian waters in the vicinity of Larak Island,” according to a Pentagon spokesman. The Iranians have boarded the ship.
