Video that purportedly shows the damage from a Yemeni missile hitting Saudi Aramco oil facility

The video was originally posted by a Houthi supporter on Facebook. The caption says.

"By the grace of Allah,
Just about an hour ago, a video from inside Najran city for #Aramco oil company burning by a Yemeni ballistic missile "Zelzal-3", Friday 26-8-2016.

The video shows a huge fire on the oil tanks .. Note the oil tanks at 00:17 of the video."

Update:

As far as we can tell, the reports may have originated from this video, which is obviously unclear. There is some talk that it's a spoof report that's recirculating reports (and perhaps videos) from an attack in Dec 2015.

Update 2: The Saudi state news agency reports that a power relay facility was set on fire by a projective fired from Yemen towards the Southern Saudi Arabian facility of Najran.

My guess is that these reports are unrelated. Najiran is 200km from Jazan. That said, it points to a larger, perhaps coordinated attack from Yemen.

But overall, I'm still not sure the report on the attack of the oil facility is credible.

Oil has trimmed gains from around 2.2% down to +0.9%.
