A suspected submarine attack on the Iranian frigate IRIS Dena off Sri Lanka's coast today has left at least 100 crew members feared dead, according to Sri Lankan naval authorities. The incident occurred in international waters southwest of Galle during early morning hours of March 4, 2026.
Initial reports indicate 180 personnel were aboard the vessel when it began sinking. The Sri Lanka Navy mobilized immediate rescue operations, saving 35 crew members who were transported to Karapitiya Teaching Hospital. Hospital Director Dr. Anjali Perera confirmed medical teams are treating survivors for hypothermia and trauma.
Foreign Minister Vijitha Herath stated: "This tragic incident underscores the need for enhanced maritime security cooperation in the Indian Ocean region." While the attack's origin remains unconfirmed, regional analysts note the waters off Sri Lanka have seen increased naval activity this year.
International responses are emerging, with the United Nations Security Council expected to convene an emergency session. The IRIS Dena's mission and full casualty details remain undisclosed as investigations continue.
