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 were found aboard the ship 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.
