An Iranian naval frigate reportedly sank off the coast of Sri Lanka following an attack from a submarine, according to Sri Lankan authorities. The incident occurred early in the morning when the vessel, identified as IRIS Dena, sent a distress signal. Sri Lanka’s navy and air force were deployed to assist in the rescue operation after receiving the alert.

Sri Lankan Foreign Minister Vijitha Herath told parliament that the ship had 180 people on board. Thirty injured sailors were rescued and taken to a hospital in Galle port for treatment. Authorities confirmed that 32 people have been located so far, while the fate of the remaining 150 crew members remains uncertain.

Rescue efforts are ongoing as Sri Lankan forces continue to search the area for survivors. Officials have not yet provided details on the source of the submarine attack or the current condition of the wreckage.
