As the war between Iran and US-Israel forces reaches the seventh day, a fresh twist has appeared in the Wednesday attack on the IRIS Dena, an Iranian warship, off the coast of Sri Lanka.

According to government sources, another Iranian naval vessel, the IRIS Lavan, had requested permission to dock in Kochi on February 28 after developing serious technical faults, a PTI report said.

The report added that it received approval on March 1 under humanitarian grounds, after which it finally docked on March 4. Its 183-member crew was housed at the Indian Navy's quarters.

The sources noted that just like the IRIS Dena, the IRIS Lavan had also been a guest for the Indian Navy's International Fleet Review (IFR) 2026, organised at Visakhapatnam back in February this year.

In retrospect, while the IRIS Lavan allegedly managed to escape being attacked by the US as it had docked at Kochi, the IRIS Dena was not so lucky.

The latter, a Moudge-class frigate, had been returning to Iran after taking part in the IFR 2026 when it was torpedoed by a US submarine, leading to the deaths of at least 87 sailors.

Hours later, US defence secretary Pete Hegseth soon clarified Washington's role in the strike, declaring that it had been destroyed as a part of Operation Epic Fury, which is the country's name for coordinated joint strikes with Israel on Iran.

The Pentagon also released visuals of the strike on the Iranian frigate, that drew sharp reactions from Iran, which has called it a "war crime". 

"IRIS Dena was a training ship. It was invited by the Indian Navy to take part in an exercise. They went there as guests. They were unarmed," Iranian Foreign Minister Abbas Araghchi wrote in an X post.
