How can killing of Muslims by Buddhists in Myanmar be justified?

Considering whatever atrocities Muslims did (I don't know if they did any) or are going to do, is killing Muslims the only solution the Myanmar Buddhists could adopt? Is it wise? Is violence recommended in Buddhism (or by Buddha) under any extreme circumstances?? If no, why have the Myanmar Buddhists chosen that path? For context, here are some news links on this topic: * [BBC: Why are Buddhist monks attacking Muslims?](http://www.bbc.com/news/magazine-22356306) * [CNN: Anti-Muslim tension simmers ahead of Myanmar election](http://www.cnn.com/2015/11/02/asia/myanmar-burma-buddhist-muslim-violence/)
