A US submarine torpedoed and sank an Iranian warship off the coast of Sri Lanka on Wednesday, the Pentagon said, as more nations were sucked into the Middle East war.
The US submarine torpedoed an Iranian warship in the Indian Ocean during an attack called "quiet death", Defense Secretary Pete Hegseth announced.
It was the first US sinking of an enemy ship by torpedo since World War II. "Like in that war," Hegseth said, "we are fighting to win."
Sri Lankan authorities said the bodies of 87 bodies of Iranian sailors had been recovered.
In the Gulf, Iran's Revolutionary Guards said they had total control of the crucial Strait of Hormuz, after President Donald Trump has said the US Navy was ready to escort oil tankers through the waterway.
Earlier, the Revolutionary Guards warned ships against entering the strait, and major shipping firms have already suspended transit through the waterway with maritime agencies reporting several ships attacked.
