TERRORISM

When will the terrorism end? I think no one can tell that. But can anyone define that what terrorism is? There is no exact definition but what I have heard through news channels is that the terrorist say that they are fighting against the injustice that their community has gone through. But I want to ask from them that is what they did on 7/7, 9/11 is justified. Why always the innocent people suffer from the terrorist attack? Why? Do they have the answer? I am sure that they don’t.
Today, there was an attack on INDIAN INSTITUTE OF SCIENCE, BANGALORE
What initial reports suggest is that it was an terrorist attack. And definitely no one can justify this. What the brightest minds in the world have done. Why they targeted them? One of the professor of WORLD RENOWNED IIT DELHI died in the attack and few others were injured.
