There are few articles that are not favorable to the IDF in there but they are few and far between. You could then also say that Aljazeera is fully factual and unbiased since they also publish negative stories about Hamas or Qatar sometimes. And I’m not even going to take the stance that Aljazeera is unbiased.
The word “cruel” in that title is not a quote. It is a word they injected there themselves.
Journalism is impartial when it doesn’t try to inject unnecessary fluff wording and presents the facts as they are. Words like “evil” or “cruel” should very rarely be used, especially in this case when somehow an announcement is cruel??
Putting every article (and even titles) full of propaganda quotes that add nothing to the factuality is not unbiased nor is it even factual as most of the IDF quotes are straight up disinformation. Nor are the attributions done to a person. A lot of the time it’s "IDF spokesperson said " at which point there’s not even a name attached to the quote.
