US submarine sinks Iranian warship off Sri Lanka, killing 87 sailors

A US submarine torpedoed and sank the Iranian frigate Iris Dena off the southern coast of Sri Lanka, killing at least 87 Iranian sailors. The vessel was in international waters returning from a naval exercise organized by India in the Bay of Bengal. The attack follows threats by the Trump administration to destroy Iran's military and political leadership, escalating conflict beyond the Middle East. Former US officials have questioned whether the strike violates international law. The incident marks a significant escalation in US-Iran hostilities, with Washington and Israel promising to hit deeper targets in Iran. The attack occurred amid ongoing Middle East crises and live updates on the conflict.

Global Impact

Geopolitically, this attack risks drawing India and Sri Lanka into the conflict, given the proximity to their waters, and could trigger a broader naval confrontation in the Indian Ocean. Economically, energy markets face immediate disruption, with potential supply chain impacts on oil tanker routes near Sri Lanka.
