I probably shouldn’t guess because the truth is I have not even the slightest idea, but I would bet money that it was the Israel side that started the violence and not the protestor side. Among other things, I think if the protestors started the violence, there wouldn’t be any of this passive voice “violence evolved” stuff; we’d be hearing specifically about how they “attacked,” in the active voice.
