Iran’s military reported that 104 crew members were killed and 32 others injured when the Iranian warship IRIS Dinar was sunk by a U.S. Navy attack near Sri Lanka’s coast on March 4. The Turkish-based Anadolu Agency cited the Iranian army’s statement, while Iran’s state news agency IRNA confirmed the incident and the casualty figures.

According to the IRNA report, the warship was returning home after participating in a naval exercise held in India when it came under attack. Washington confirmed that a U.S. submarine launched a torpedo strike that caused the vessel to sink. Sri Lankan authorities said they began a rescue operation immediately after receiving a distress signal from the ship, rescuing 32 crew members who were later hospitalized.

The incident marks a severe escalation in tensions between the United States and Iran, though no further official responses or diplomatic actions were detailed in the reports.
