I wouldn’t say fair. They are a state-owned press agency, and accordingly their material should be read in the context of how it aligns with the views of the Qatari government.
But they do have a perspective they report from, and that perspective deserves to be voiced just as much as any of the more western-aligned publications. Like most stories, the truth probably lies somewhere in the middle, so I see them as a check on otherwise one-sided accounts of the Middle East.
