It is for the people to ensure they do not give protection in any manner to the militants, extremists and point out the suspected person to the law enforcing and security related agencies personnel so that the menace in uprooted as early as possible.
People should be courageous and brave enough to say pretty loudly there is no room for extremists, terrorists and militants as our religion Islam preaches middle of the road, avoiding extreme stances and strongly prohibits killing innocent people who do not subscribe to a peculiar point of view.
