A Yemeni official had told Reuters that Saudi Arabia and its main ally the United Arab Emirates would likely seek to remain deployed along the country's Red Sea coast, where it is now fighting an offensive against the Iran-aligned Houthi movement.
Meanwhile, the Saudi coalition fighting the Houthis in Yemen said its air defences shot down two unmanned drones in the south of the country.
Yemen's armed Houthis said on Wednesday they had launched a drone strike on a facility belonging to oil giant Saudi Aramco in southern Saudi Arabia, Reuters reported.
Houthis claimed the attack on Twitter, saying the intended target of the attack was the Saudi defense ministry in Riyadh.
The news agency said that Saudi Aramco was building a refinery in Jizan planned to produce 400,000 barrels of oil a day from 2019.
While in Saudi Arabia, he reportedly plans to meet several Saudi-based Yemen officials, including President Abd Rabbuh Mansur Hadi, who has resided in Riyadh for the past several months.
The kingdom and its mostly Gulf Arab allies intervened in a civil war in Yemen in 2015 to roll back the Houthis after they had pushed the government into Saudi exile. That same year in June, 17 Sudanese soldiers were killed and dozens more wounded at Midi of Hajjah province, in north-west Yemen.
The United Nations says 10,000 people have died in the three-year-old war, and three out of four Yemenis - 22 million civilians - need relief aid.
Sudanese Foreign Minister Ibrahim Ghandour stressed on Tuesday that his country will remain part of the Saudi-led Arab coalition aimed at restoring legitimacy in Yemen. Turki al-Maliki, said that at 7:40 am local time, air defense systems were able to detect an unidentified object in the direction of Abha International Airport and was dealt with accordingly.
The arms monitor Conflict Armament Research (CAR) said it had evidence showing the Qasef-1 and other Houthi kit was made in Iran and was not of indigenous design and construction "in contrast to Houthi statements".
Al-Arabiya quoted al-Malki as describing the drone over Abha airport as a "hostile Houthi aircraft with Iranian characteristics".
