Is Yemen heading for a new war? Fragile truce crumbles over a controversial Iranian flight

Yemen is heading towards a new and imminent phase of full-scale fighting. The fragile truce that had maintained relative calm since April 2022 under UN mediation is at an all-time low due to the escalation of political and military tensions between the internationally recognised Yemeni government and the Iran-backed Houthi movement.

The trigger for this latest crisis has been the arrival of a direct Iranian flight at Sana’a airport, the first to be publicly announced in nearly a decade. What began as a dispute over control of airspace has rapidly mutated into a profound geopolitical crisis, reactivating warmongering rhetoric and triggering troop mobilisations across multiple fronts in the country.

The flight of discord: Iranian provocation or humanitarian mission?

The controversial landing in Sana’a has reactivated the Middle Eastern geopolitical chessboard:

• The stance of the Government of Yemen and the Saudi Coalition: They denounce that the aircraft is directly linked to Iran’s Islamic Revolutionary Guard Corps. They claim the flight violates national sovereignty, breaches UN Security Council resolutions, and represents an explicit demonstration of influence and interference by Tehran on Yemeni soil.
• The stance of the Houthis: They reject the accusations and maintain it was a strictly civilian and humanitarian mission. Furthermore, they claimed to have confronted Saudi warplanes that attempted to intercept and block the aircraft’s landing.

General mobilisation and preparations for battle

Faced with what the legitimate government describes as a “new escalation”, the president of Yemen’s Presidential Leadership Council, Rashad al-Alimi, convened an emergency meeting in Riyadh with high-ranking State officials to reinforce the armed forces and consolidate the internal front.

For their part, the Houthis have responded with a display of military power, declaring a general mobilisation and organising massive armed parades in the strategic provinces of:

• Saada
• Hajjah
• Al-Jawf (where tribal fighters have already shot down a Houthi reconnaissance drone)
• Dhamar
• Marib
• Hodeidah

Leaders of the rebel movement are urging their ranks to prepare for what they term the battle for “national independence” and the definitive end of the economic blockade.

Saudi Arabia warns of an “unprecedented” response

The exchange of threats has reached critical levels. The Houthis have formally warned that their forces could launch targeted attacks against airports and strategic installations within Saudi Arabian territory if they face an offensive.

The response from the Riyadh-led coalition was swift. Military spokesperson Turki al-Maliki dismissed the Houthi warnings, labelling them a diversionary tactic to distract from their internal problems, but warned that the coalition will respond “with full force and unprecedented firmness” to any threat to Saudi or Yemeni security.

Expert analysis: The 2022 truce only served to freeze front lines and postpone the conflict rather than resolve it. During these years, both sides have taken advantage of the calm to rearm, recruit fighters, and reposition forces while core disputes — such as power-sharing, control of resources, and Houthi disarmament — remain untouched.

An imminent danger to international maritime trade

Diplomats fear that Yemen is at a crossroads of no return. Should international efforts to contain this crisis fail, the breakdown of the truce will not only restart the civil war but will also internationalise the conflict, bringing direct and severe consequences for Red Sea security, international shipping, and the energy stability of the Arabian Peninsula.
