Peace will never be brought in this world through violence, so it is better to deal each other with clam and through non-violence.
Best is think that we all are same human being with good loving heart and soul. I feel very sad to see and watch many people around the world dying every moment by some means that is either by some terrorists or by their own loving mates.
Think carefully, and be a better human being.
I pray that not to happen such bitter incidents in and around the world.
