US Submarine Sinks Iranian Warship IRIS Dena Near Sri Lanka Amid Rising Tensions

The US Defense Secretary Pete Hegseth confirmed that a US submarine torpedoed and sank the Iranian warship IRIS Dena in international waters near Sri Lanka, marking the first US torpedo sinking of an enemy ship since World War II. Approximately 80 to 150 Iranian sailors are feared dead, with survivors rescued by Sri Lankan authorities. The IRIS Dena had recently participated in India's naval exercise MILAN 2026. The US and Israel have intensified military operations against Iran, with Tehran threatening retaliatory strikes in the Middle East. Indian political leaders have questioned the implications of the incident near India's strategic waters.
