An Iranian naval frigate, the 'Dena,' is suspected to have been attacked by a submarine in the waters south of Sri Lanka, potentially resulting in the deaths of 100 people. According to RTHK, Sri Lankan media reported that the incident occurred on Wednesday morning off the coast of Galle, with approximately 180 crew members aboard the vessel. The Sri Lankan Navy dispatched ships for a rescue operation, successfully saving 35 individuals who were then transferred to a hospital in Galle. Reports cite the Sri Lankan Foreign Minister stating that the waters where the 'Dena' encountered trouble do not fall within Sri Lanka's territorial sea.
