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. Aden International Airport was recaptured on July 14 by Gulf Arab-backed forces as they drove Yemeni forces out of the southern port city and much of the surrounding areas, Reuters reported. 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 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.
