According to the U.S. Department of Defense, an American submarine sank an Iranian vessel off the coast of Sri Lanka. The Iranian warship that was sunk is identified as the Iris Dena. The attack occurred in international waters off Sri Lanka's coast. A video was released by the U.S. showing a torpedo from an American submarine hitting an Iranian warship near Sri Lanka in the Indian Ocean.
Casualty figures from the attack are disputed. According to U.S. and major media sources, the attack resulted in 87 deaths and 32 rescued sailors. However, other sources report a different toll. Sri Lanka's deputy foreign minister stated on local television, 'At least 80 people were killed in the attack.' Earlier reports had estimated 140 people missing. Iranian officials claim the Iris Dena had 'almost 130' crew members, adding to the uncertainty over the final death count.
The status of the Iris Dena at the time of the attack is sharply contested. U.S. officials claim the Iris Dena was a military target. In contrast, Iranian officials claim the Iris Dena was unarmed and ceremonial. The Iranian ship was heading back to Iran from a port in eastern India. Legal experts note that targeting a military vessel is not a war crime, but post-attack rescue obligations may raise concerns. The U.S. contacted Sri Lankan authorities for search and rescue, though the extent of these efforts remains unclear.
In the aftermath, two other Iranian warships have retreated from an Israeli-American area or operation, according to the U.S. Department of Defense. Meanwhile, a second Iranian ship is approaching Sri Lanka with over 100 crew. Sri Lanka is considering Iran's request for this second ship to enter its territorial waters, a decision that could impact regional tensions.
Australian involvement in the incident has been clarified by their government. Three Australian personnel were aboard the U.S. submarine as part of AUKUS training. Prime Minister Albanese confirmed that these personnel did not participate in the offensive action. They were sent to their cabins during the operation, highlighting the collaborative nature of the AUKUS alliance while distancing Australia from direct combat roles.
The incident has sparked international concern, with analysts warning it could escalate tensions in the Indian Ocean region. The U.S. has defended the attack as a necessary defensive measure, while Iran has condemned it as an act of aggression. The release of the video footage by the U.S. is seen as an attempt to justify the action, though its authenticity has not been independently verified. Sri Lanka, caught in the middle, faces diplomatic challenges in balancing relations with both nations while managing the humanitarian aspects of the attack.
Further details on the timeline of events remain scarce. The U.S. has not disclosed the specific circumstances that led to the decision to fire the torpedo, nor has it provided a full account of the Iris Dena's activities prior to the attack. Iranian officials have called for an international investigation, but no such inquiry has been initiated yet. The incident underscores the volatile nature of naval encounters in strategic waterways and the potential for miscalculation between adversarial forces.
