Yemeni government says one of the missiles hit Aden airport’s runway minutes before a flight from Cairo was due to land.

Yemen’s internationally recognised government has accused the Houthis of firing ballistic missiles and drones at the main international airport under its control, as Saudi Arabia said it had intercepted another missile north of its capital, Riyadh.

In a statement on Wednesday, the Ministry of Transport said the Houthis targeted the runway and passenger terminal at the airport with at least two ballistic missiles and several drones.

“One of the missiles landed near the runway minutes before the Yemeni flight from Cairo was to land,” it said. “We cancelled the landing of the incoming flight from Cairo [in Egypt] and diverted its route to Jeddah [in Saudi Arabia] to protect the passengers.”

The ministry also said it evacuated the airport terminal and removed two planes from the tarmac during the attacks.

It added, “This incident could easily have turned a civilian flight into a horrific humanitarian disaster, claiming the lives of dozens of innocent people in an instant.”

Aden airport is the main international gateway for parts of Yemen outside Houthi control in the city that has been the seat of the government since the takeover of the capital, Sanaa, by the Iran-supported group in 2014.

The Houthis said in a statement they targeted “Saudi military supplies” arriving at the Badr camp near the airport with ballistic missiles. Saudi Arabia backs Yemen’s government.

Separately, the Saudi-led military coalition fighting in Yemen said it intercepted and destroyed a ballistic missile, launched by the Houthis, north of Riyadh.

In a social media post, Major-General Turki al-Maliki, the spokesperson for the Saudi-led coalition, said it was tracking the launch platform used in the attack via an intelligence system over Sanaa, and promised to destroy it.

The Houthis said in statements on Tuesday and overnight into Wednesday that they had targeted Saudi international airports in Riyadh and Abha.

The intensified fighting in Yemen comes amid mounting regional tensions set off by the US-Israel war on Iran. The Saudi-backed government forces launched a counteroffensive against the Houthis to retake the Red Sea port of Mocha and areas around the Bab al-Mandeb strait.

Fighting has concentrated in the southwestern province of Taiz.

Al Jazeera’s Yousef Mawry, reporting from Sanaa, described “all-out battles to take over the ground, the highlands and the mountains east of Bab al-Mandeb”.

“It’s a battle to take over the strategic western part of Taiz, and whoever controls the wider vicinity will overlook the region and have dominant military control,” he said.

“For the Yemeni government to take control of Mocha and the strategic bases and locations along the Red Sea coast, it first has to drive the Houthis off the mountains east of Mocha.”

Pakistan and Turkiye on Monday agreed to activate “deterrence measures” under their mutual defence pact with Saudi Arabia and rapidly deploy forces to the Gulf kingdom to counter Houthi attacks.
