Australia and India Grapple with Fallout of US Submarine Attack on Iranian Navy Frigate

Australia and India React to Sinking of IRIS Dena Off Sri Lanka

The US submarine sank the Iranian navy frigate IRIS Dena off the coast of Sri Lanka, resulting in the deaths of 148 crew members. Australian sailors were on board the submarine, but Prime Minister Anthony Albanese denied their involvement in the attack. The incident has sparked controversy in the Indo-Pacific, with Australia and India grappling with the fallout. The US-India relationship may be impacted due to domestic pressure in India, but it is unlikely to result in a severing of security ties. The incident highlights the complexities of international naval law and the roles of personnel on US submarines in combat situations. The sinking of the Iranian ship may strain relations between the US and India, particularly given the ship’s recent participation in a multinational naval exercise in India. The incident was reported by Breaking Defense.
