Alwaght- Yemeni Drones have hit on Saturday two oil facilities run by Saudi Arabia's state oil giant Aramco, causing huge fires.
A spokesman for Saudi Arabia's interior ministry said in a statement that the attacks targeted two Aramco factories in Abqaiq and Khurais, in the kingdom's east.
"At 4.00am (01:00 GMT) the industrial security teams of Aramco started dealing with fires at two of its facilities in Abqaiq and Khurais as a result of ... drones," Citing an interior ministry spokesperson, the official Saudi Press Agency said.
The statement did not identify the source of the attack, but Yemen's Ansarullah movement later claimed responsibility in an announcement on Al Masirah TV.
The movement's military spokesman General Yahya Sare'e said 10 drones were deployed against the sites in Abqaiq and Khurais, and pledged to widen the range of attacks on Saudi Arabia.
"This was one of the largest operations which our forces have carried out deep inside Saudi Arabia. It came after careful intelligence and cooperation with honorable and free people inside Saudi Arabia," he said without elaboration.
Saudi Arabia and a coalition of its vassal states launched the war on Yemen in March 2015 in an attempt to reinstall a Riyadh-backed former regime and eliminate the Ansarullah movement, which has been defending the country along with the armed forces.
Abqaiq, about 60 km (37 miles) southwest of Dhahran in Saudi Arabia's Eastern Province, contains the world's largest oil processing plant. Most Saudi oil exported from the Persian Gulf is processed there.
The incident comes nearly a month after Saudi Aramco’s oil facilities in Shaybah, the kingdom’s largest strategic oil reserve near the UAE border, were targeted by Yemeni forces in a major drone attack.
Yemeni forces also launched a successful raid on a major pipeline spanning the kingdom in May.
The Saudi-led war has so far turned into a quagmire for Riyadh, with Yemeni forces increasingly using sophisticated weaponry in retaliatory attacks. The UAE, Saudi Arabia’s most notable partner in the conflict, has consequently announced the gradual withdrawal of its troops from country, largely because it believes the war has become "unwinnable", according to US reports.
