US Submarine Sinks Iranian Warship Near Sri Lanka, Killing 87; Second Ship Seeks Entry

A US submarine sank the Iranian warship IRIS Dena in international waters near Sri Lanka, killing at least 87 sailors and rescuing 32, with dozens still missing. The vessel had recently participated in India's MILAN 2026 naval exercise and was returning home. Iran condemned the attack as an atrocity and warned of consequences. Sri Lanka and India launched search and rescue operations, while a second Iranian ship sought entry into Sri Lankan waters amid regional security concerns.
