Iran raises prospect of wider war reaching Indian Ocean

Thursday 24 September 2026 - 17:00

Iran has issued one of its broadest warnings yet about the possible geographic expansion of the Middle East conflict, with a senior adviser to Supreme Leader Mojtaba Khamenei saying that further US military action could push the confrontation as far as the Indian Ocean.

Yahya Rahim Safavi, a senior adviser to the Iranian leadership, made the remarks in a video released by Iran’s Fars news agency. He said the conflict had already extended from the Persian Gulf and the Strait of Hormuz to the Red Sea and could spread even farther if hostilities resume.

The statement marks a notable shift in the geographical scope of Iranian warnings. Previous threats had focused primarily on the Gulf and surrounding waterways, while the reference to the Indian Ocean brings a much larger maritime area into the discussion.

Strategic waterways at the center of the confrontation

The warning comes as the Strait of Hormuz and the Bab el-Mandeb Strait remain central to the regional crisis. Hormuz is a critical route for international energy shipments, while Bab el-Mandeb connects the Red Sea with the Gulf of Aden and forms part of the maritime corridor linking Asia and Europe through the Suez Canal.

The Houthis in Yemen have recently expanded their control along the country's Red Sea coastline and around Bab el-Mandeb. The development has added another layer to an already complex regional confrontation. Iran has provided long-standing military support to the Houthis but continues to deny direct involvement in their operations in Yemen.

The strategic importance of these waterways has increased further as Iran maintains restrictions around the Strait of Hormuz. Tehran has linked any possible reopening of the passage to conditions including reduced US military pressure and changes to the blockade imposed on Iranian ports.

Diego Garcia adds a strategic dimension

Safavi's reference to the Indian Ocean is particularly significant because the region is home to Diego Garcia, a strategically important US-British military facility.

The island lies roughly 4,000 kilometres from Iran and serves as a major military position in the Indian Ocean. The possibility of the conflict reaching this wider maritime zone therefore introduces a new geographical dimension to the confrontation, although Safavi's statement was a warning rather than an announcement of a specific military operation.

Diplomacy continues alongside military tensions

The warning was issued as Iranian and US officials continued diplomatic contacts in New York on the sidelines of the United Nations General Assembly.

Tehran has presented conditions for a broader diplomatic settlement, including the lifting of economic sanctions and the release of Iranian assets held abroad. Iranian officials have also linked the situation in Yemen to their demands concerning the continuation of hostilities.

At the same time, recent exchanges between Washington and Tehran have shown that diplomatic efforts remain closely intertwined with military pressure. Iran has repeatedly warned against renewed US attacks, while the United States and its regional partners continue to focus on maritime security and the protection of strategic shipping routes.

A widening maritime crisis

The latest warning highlights how the conflict has increasingly moved beyond a confrontation centered on land and into some of the world's most important maritime corridors.

For international shipping and energy markets, any further escalation around Hormuz, Bab el-Mandeb or the wider Indian Ocean could create additional uncertainty. Recent developments have already contributed to disruptions in regional energy flows and pushed oil prices higher amid concerns over the security of maritime routes.

Whether the latest Iranian warning leads to further military escalation remains uncertain. For now, it underscores the increasingly interconnected nature of the conflict, in which developments in the Persian Gulf, Yemen, the Red Sea and the Indian Ocean are becoming part of the same broader strategic equation.
