"Surely as a responsible news site you need to be impartial - or you need to publish it under 'Comment' rather than 'Policy' and make it clear it represents the view of the writer?"
One can be unbiased and still not be neutral. If one person is lying and the other is telling the truth, the unbiased viewpoint is "A is a liar". The neutral viewpoint is "Both A and B are saying things."
In this case, the unbiased viewpoint is that this is an outrage, the kind of thing we read about in Turkey or India (very recently) and call an outrage there.
