(AP Photo/Julia Demaree Nikhinson) 2026-04-21T12:24:10Z WASHINGTON (AP) — U.S. forces have boarded an oil tanker previously sanctioned for smuggling Iranian crude oil in Asia, the Department of Defense said Tuesday. In a social media post, the Pentagon said U.S. forces “conducted a right-of-visit maritime interdiction” and boarded the M/T Tifani “without incident.” It’s the latest move in the U.S. war on Iran to stop any ship tied to Tehran or those suspected of carrying supplies that could help its government, from weapons and oil to metals and electronics. The announcement comes hours ahead of the expiration of an already tenuous ceasefire between the U.S. and Iran, and as Pakistan attempts to broker talks between Washington and Tehran. Ship-tracking data showed the Tifani was carrying oil in the Indian Ocean on Tuesday between Sri Lanka and Indonesia. The Pentagon described the Tifani as “stateless” despite it being a Botswana-flagged vessel. The announcement did not say precisely where or what time Tuesday the ship was boarded. freestar.queue.push(function () { window.fsAdCount = window.fsAdCount + 1 || 0; let customChannel = '/dynamic_' + fsAdCount; let adList = document.querySelectorAll(".fs-feed-ad") let thisAd = adList[fsAdCount]; let randId = Math.random().toString(36).slice(2); thisAd.id = randId; let thisPlacement = fsAdCount == 0 ?

Dan Caine, chairman of the Joint Chiefs of Staff, said last week that the U.S. blockade would extend beyond Iranian waters and the war theater under control of U.S. Central Command. /* Desktop-first: fully collapse by default */ #ap-readmore-embed { display: none;
