Two Saudi aircraft landed at Aden on Friday bringing equipment needed to re-open the city's airport four months after the Yemeni civil war shut it down, Saudi-owned Al Arabiya TV reported.
Aden International Airport was recaptured on July 14 by Gulf Arab-backed Yemeni forces as they drove Iranian-allied Houthi forces out of the southern port city and much of the surrounding areas.
Houthi fighters allied with army units loyal to former President Ali Abdullah Saleh captured Aden in March and April at the outset of the country's four-month-old war, dealing a blow to President Abd-Rabbu Mansour Hadi, an ally of Saudi Arabia and the United States.
Hadi and his aides fled to Riyadh as Houthi forces, who had seized the capital in September, closed in on Aden. In the wake of Aden's recapture, his ministers are slowly returning there.
If the airport resumes regular operations using the equipment carried by the plane that landed on Friday, then the city is expected to be able to expedite the import of badly needed emergency humanitarian aid.
Four months of air raids and civil war have killed more than 3,500 people in Yemen. Aden has suffered especially, with acute shortages of food, medicine and fuel.
Aden and the other southern provinces have been largely inaccessible to U.N. food aid, and about 13 million people - more than half the population - are thought to be in dire need of food.
A coalition of Arab states has been bombarding Houthi forces since late March in a bid to reinstate Hadi. It has also run training programs for Yemeni soldiers loyal to Hadi and dropped arms to local forces fighting the Houthis.
The first plane to land at Aden airport since pro-Hadi government forces took over was Saudi, carrying weapons and military assistance. An aircraft from the United Arab Emirates (UAE), at dawn on Friday landed at Aden airport carrying humanitarian aid, Al Arabiya TV reported.
In the latest military action, coalition warplanes bombed targets across Yemen including the capital Sanaa on Friday, according to Houthi media Saba news and security sources.
They bombed several districts in Aden, including Dar Saad, Hael and al Khadra and targets in Marib, Shabwa, Abyan, Taiz and Amran provinces.
