Iran’s New Air Bridge to Yemen

On July 13, Iran defied repeated warnings from Yemen’s internationally recognized government and attempted to return a Houthi delegation to Yemen aboard a Mahan Air aircraft. When the plane continued toward Sana’a, the Yemeni government said it had struck the airport runway to prevent it from landing. The aircraft ultimately diverted to Hodeidah and landed there successfully.

The message was unmistakable: Iran was testing a red line, challenging Saudi Arabia and the Yemeni government while attempting to establish a new reality on the ground. Tehran understands that its neighbours have little appetite for escalation. Between February and June 2026, Iran and its proxies launched over 7,000 missiles and drones against Gulf countries, targeting military facilities, airports, ports, energy infrastructure, and civilian areas. Yet Gulf responses largely emphasized condemnation, diplomacy, and de-escalation, including relying on Omani mediation and diplomatic channels to contain the crisis and prevent further escalation.

Saudi Arabia’s preference for de-escalation did not emerge in a vacuum. It followed years of costly Houthi missile and drone attackson Saudi cities, airports, oil infrastructure, and military facilities that ultimately helped pave the way for the 2022 truce between Riyadh and the Houthis. Tehran is betting that, once confronted with an established reality, its neighbours will ultimately adjust.

On July 2, a Mahan Air aircraft landed in Sana’a, marking the first direct flight between Iran and Houthi-controlled Yemen since the outbreak of the war in 2015. The aircraft carried a Houthi delegation to Tehran to attend the funeral of Iran’s Supreme Leader Ali Khamenei. At the time, Yemen’s Presidential Leadership Council condemned the flight as “a blatant violation of the sovereignty of the Republic of Yemen and a flagrant challenge to international law and the relevant UN Security Council resolutions.” Over the following days, Iran and the Houthis insisted that the delegation return aboard the same Mahan Air aircraft, despite objections from the Yemeni government.

The dispute was never really about civilian aviation or simply returning a Houthi delegation from Tehran. The Yemeni government had agreed to facilitate the delegation’s return to Sana’a aboard a Yemenia Airways aircraft. The issue lay in what Mahan Air represented. The airline was designated by the U.S. Treasury in 2011 for acting as a logistical arm of the Islamic Revolutionary Guard Corps (IRGC), transporting personnel, weapons, and equipment to Iran’s regional partners and proxies. For Tehran, the issue was not merely the return of a delegation, but the normalization of direct Iranian access to Houthi-controlled Yemen. Accepting a Yemenia aircraft would have acknowledged the Yemeni government’s sovereignty over the route. Insisting on a Mahan Air flight sent a different message entirely: Iran intended to establish its own channel to the Houthis for political, logistical, and potentially military support — and expected the region to adapt to it.

The Houthis quickly reinforced that message. In an official statement, they accused Saudi Arabia of carrying out the strikes on Sana’a airport, described them as a violation of the 2022 truce, and warned that the attack “will not go unanswered. “The message was equally clear: efforts to challenge this new reality would carry risks of escalation of their own.

The incident came amid renewed escalation between the United States and Iran. A day earlier, Iran had launched attacks across several Gulf states and Jordan in retaliation for a new wave of U.S. strikes on Iranian targets.

The Mahan Air episode should therefore not be viewed in isolation but as part of a broader Iranian strategy that combines calibrated escalation with political messaging to reshape the regional security environment in its favor. Washington’s assumption has long been that military pressure would force Tehran to back down or change course. Iran, however, has repeatedly shown an ability to turn confrontation into leverage while improving its own strategic position.

Similar dynamics have played out in the Strait of Hormuz, where Tehran has used coercive pressure not simply to retaliate, but to alter the calculations of its adversaries, demonstrate its ability to impose costs, and strengthen its bargaining position. This tactic paid off. The U.S.-Iran Memorandum of Understanding went beyond de-escalation by recognising a leading role for Tehran in defining the future administration and maritime services of the Strait of Hormuz alongside Oman and in consultation with other Gulf states, effectively playing into Iran’s hands.

The normalization of direct Iranian access to Houthi-controlled Yemen extends far beyond political symbolism. Reports surrounding the July 2 Mahan Air flight suggested that the aircraft may also have transported specialists and sensitive equipment into Sana’a, including missile parts, alongside the Houthi delegation. Sources also indicate that dozens of IRGC officers and experts arrived in Yemen on the flight, some accompanied by their families.

As Iran comes under growing military pressure and scrutiny from the United States and Israel, the Houthis and Yemen offer Tehran something increasingly valuable: strategic depth beyond Iran’s borders and a platform from which to project influence into the Red Sea, the Gulf, and the Horn of Africa. This is particularly important as the Houthis are increasingly spearheading Iranian efforts to expand smuggling, recruitment, and operational networks across the Red Sea and the Horn of Africa. More importantly, embedding personnel, expertise, and infrastructure inside Yemen creates capabilities that are far more difficult for the United States and its partners to monitor, disrupt, or roll back than those located inside Iran itself.
