The terror attacks in Sydney and Peshawar have spawned a series of central advisories alerting the states and Union territories to the possibility of lone-wolf attacks as well as a strike by a group of five SIMI activists on the run.

After the Intelligence Bureau alerted Delhi, Maharashtra, Karnataka and Andhra Pradesh on Monday about a likely lone-wolf attack based on a warning tracked on a pro-ISIS Twitter handle, the Union home ministry issued a fresh advisory on Tuesday to all states and Union territories seeking tighter surveillance and policing in the light of a heightened terror threat to crowded places and emphasize on a standard drill laid down in 2010 to insulate schools against terror attacks.
