US Submarine Sinks Iranian Warship Near Sri Lanka

A US Navy submarine sank the Iranian warship IRIS Dena in the Indian Ocean near Sri Lanka, marking the first use of a torpedo by the US since World War II.

Subsequently, the United States and Iran disputed the status of the IRIS Dena's armament at the time of the attack. The incident highlighted the complexities of maritime neutrality in the region and drew comparisons to historical naval conflicts. The sinking has escalated regional tensions and raised questions about naval engagement rules near neutral waters.
