Aljazeera is not a legitimate source, specifically regarding this conflict and the Israeli Palestinian problem. If you intentionally are choosing this source aware of that you're being intellectually disingenuous.
They are state owned by Qatar and have an agenda that clearly and demonstrably biases their coverage. It exists explicitly to further the interest of Qatar.
If you're unclear why that makes it an illegitimate news source on the Israeli Palestian conflict, then I'm not sure how to help you.
The same could be said for any source. No news agency is truly independent. Every news agency is beholden to the government where it operates, its owners if it is privately owned, its advertisers if it advertises, and its subscribers if it has paid subscriptions. I’m not gonna try and argue that the Qatari government is better than any other entity to be beholden to, but there’s nothing unusually wrong about their perspective or bias either. On Middle East matters, I think it’s especially important to have a Middle East voice expressing their viewpoint.
