The United States Department of Defense has released footage showing one of its submarines firing on and sinking an Iranian warship in the Indian Ocean. Sri Lankan authorities say the vessel sent out a distress call before it went down. Police and defence officials in Sri Lanka report that 87 bodies have been recovered, with 67 sailors still missing.

The sinking comes amid a sharp escalation in regional tensions. Iran has launched missile and drone attacks on several countries as Israel and the United States continue to strike targets inside Iran. The developments mark a significant widening of the conflict, raising fears of further instability across the region.

Reporting from eastern Turkey indicates that some Iranians have been crossing the border as the situation intensifies. There are also questions about whether Kurdish forces could mount an insurgency aimed at toppling the government in Tehran, adding another layer of uncertainty to an already volatile crisis.
