Iranian naval commander Shahram Irani said state television on Thursday that his navy forced a US submarine to surface as it entered the Gulf, the latest story of an apparent clash between Iranian and US forces in the Gulf.

“As the US submarine approached while submerged, the Iranian submarine Fateh detected it and performed… maneuvers to force it to surface as it passed through the Strait of Hormuz.” It had also crossed our territorial seas, but after being warned, it changed direction,” Irani added.

“This submarine was doing its best, using all its capacities, to pass in total silence and without being detected,” Irani said. “We will certainly reflect to international bodies the fact that it had violated our border.”

The U.S. Navy said earlier this month the nuclear-powered, guided-missile submarine Florida was operating in the Middle East in support of its Fifth Fleet, based in Bahrain.

There was no immediate comment from the U.S. military to Irani’s remarks. Reuters sent a message seeking comment from the Fifth Fleet.

Iranian and U.S. forces have had a number of confrontations in the past. In early April, the Iranian navy said it identified and warned off a U.S. reconnaissance plane outside the mouth of the Gulf. In 2019, Iran shot down a U.S. drone which it said was flying over southern Iran.
