An adviser to Iran's supreme leader Mojtaba Khamenei warned on Thursday (September 24, 2026) that Tehran may expand the West Asia war to the Indian Ocean if the U.S. attacks again.

We have been victims of terrorism: Iran President tells UN in rare wartime address "Since the conflict has spread from the Persian Gulf and Strait of Hormuz to the Red Sea, it is possible that, in response to more war, the front will expand even further, reaching the Indian Ocean and perhaps beyond," said Yahya Rahim Safavi in a video released by Iran's Fars news agency.

Yemen's Houthis, fighting Saudi-backed government forces, recently took control of the Red Sea coastline, tightening their grip on the strategic Bab al-Mandab Strait, which links Asia to Europe via the Suez Canal.

Iran has long provided military support to the Houthis but denies any involvement in the Yemen conflict.

Hope for progress after U.S., Iran hold first shuttle talks in months The Islamic republic has also locked down the Strait of Hormuz off the Iranian coast, in retaliation for U.S.-Israeli strikes that triggered the West Asia war at the end of February.

Iran and the United States are now vying for control of Hormuz, through which much of the world's oil and gas passed before the war.

Iranian officials had already threatened to expand the geographic scope of the conflict if U.S. strikes resume.

Yemen's Houthis to target U.S. interests if it supports Saudi-led strikes: Houthi military adviser But Thursday's (September 24, 2026) warning is the first time an adviser to Iran's supreme leader explicitly mentioned the Indian Ocean, home to a strategic U.S.-British military base at Diego Garcia, nearly 4,000 kilometres from Iran.

Officials from both countries held talks in New York this week on the sidelines of the UN General Assembly in a further attempt to end the conflict.

Iran has put forward its conditions for ending the war, including the lifting of sanctions targeting its economy and the unconditional release of its frozen assets abroad.

In an exclusive interview with AFP on Tuesday (September 22, 2026), a spokesman for Iran's Revolutionary Guards, Hossein Mohebi, also mentioned ending the war in Yemen.
