SANAA, Sept. 4 (Xinhua) -- Yemen's Houthi forces on Tuesday fired four ballistic missiles at the facilities of Saudi oil giant Aramco in the border city of Jizan, the Houthi-controlled Saba news agency reported.
Meanwhile, the Saudi-owned Al Arabiya TV reported that the Saudi air defenses intercepted and destroyed two ballistic missiles over Jizan.
The Saudi TV did not provide details about the other missiles claimed by the Houthi militias.
On Monday, the Houthis said they launched a ballistic missile at economic targets in Jizan.
Yemen has been locked in a civil war since late 2014, when the Houthi rebels overran much of the country and seized all northern provinces, including the capital Sanaa.
Saudi Arabia is leading an Arab military coalition that has intervened in the Yemeni war since 2015 to support the Yemeni elected government of exiled President Abd-Rabbu Mansour Hadi.
The war has so far killed more than 10,000 Yemenis, mostly civilians, and displaced about 3 million others.
