U.S. submarine sinks Iranian warship off Sri Lanka, dozens killed

A U.S. submarine sank an Iranian warship off the coast of Sri Lanka. The U.S. defense secretary confirmed the incident, which reportedly killed at least 87 sailors, while the Sri Lankan Navy rescued 32 others.

This is described as the first sinking of an enemy warship by a U.S. submarine since World War II. The event expands the zone of direct naval conflict between the U.S. and Iran beyond the Middle East into the Indian Ocean.
