Considering how it was flying on the video, it is most probably downed. But I'm a mere random citizen, I may be wrong.
That doesn't looks like a typical final nose dive attack pattern like we see on all those refineries strikes, more like an out of control UAV after being struck by air defense.



Yeah, sure, RT, Russia well known propaganda outlet, will be a good source for such event. 🙃
I'm gonna wait for actual journalists to cover that event.
