This is really sad. I really think the leaders of all sides should calm people down. It is not enough to say "calm down". Direct and guide those people, isn't it the leader's job and vocation?
Hitting each other and beating up each other is not the answer. Killing is not the answer out of anger and desperation. Count to 10 before you burst out against someone who only thinks differently from you in a political way, it is not worth it. Count to 10, pray to your God, and leave. Have patience.
One has already died. Let him be the last one.
