​ US sub sinks Iranian warship in Indian Ocean, Hegseth says. 9 hours ago. Yogita Limaye,South Asia and Afghanistan correspondentand. Alys Davies. US Secretary of Defense Pete Hegseth has said an American submarine sank an Iranian warship in the Indian Ocean.. He said the ship was sunk by a torpedo on Tuesday, and that it died a “quiet death”.. Hegseth did not name the ship, but his announcement came after Sri Lankan officials said its navy had responded to a distress call from an Iranian ship on Wednesday morning named the Iris Dena, which had gone down about 40km (25 miles) from its southern coastline.. Eighty bodies from the ship were found by rescuers, a Sri Lankan defence official told BBC Sinhala. Another 32 were rescued, the Sri Lankan navy said.. A navy spokesman said some 180 people were believed to have been aboard the Iris Dena, based on the ship’s documentation.. The survivors were “seriously injured” and had been taken to a hospital in the southern port of Galle, foreign affairs minister Vijitha Herath said.. Hegseth told a news conference on Wednesday thata US submarine had sunk an Iranian warship “that thought it was safe in international waters”.. He also claimed it was “the first sinking of an enemy ship by a torpedo since World War Two”.. While it is the first time since 1945 that an American submarine has sunk an enemy ship this way, the UK and Pakistan have both sunk vessels using torpedoes since then.. Video released by the US Department of Defense shows a ship being struck, causing the stern to rise up before exploding.. Earlier, Sri Lankan navy spokesman Budhika Sampath rejected reports that the Iris Dena had been attacked by a submarine.. He added that, at the time rescue operations were launched, rescuers had not seen the vessel – nor any other ships in the region – but saw oil patches and life rafts floating on the water.. Though the ship’s location “was beyond our waters”, Sampath said, “it was within our search and rescue region. So we were obliged to respond as per international obligations”.. AP. First launched in 2015, the Iris Dena is a destroyer attached to Iran’s Southern Fleet, which is tasked with deployments in the Strait of Hormuz and Gulf of Oman.. It had recently participated in International Fleet Review 2026, a military exercise hosted by India.. The sinking of the Iris Dena comes as the US and Israel have continued to launch air strikes on Iran for a fifth day, with the Israeli military saying it had hit “security headquarters” across the capital, Tehran, on Wednesday.. Israel has also conducted air strikes on Lebanon and has sent ground forces into the south of the country after armed group Hezbollah launched rockets and drones at Israel.. Iran appears to have continued to carry out retaliatory attacks. New strikes were reported in Saudi Arabia and Kuwait on Wednesday, while Turkey said “Nato defences” shot down an Iranian missile heading towards Turkish territory..
