In desperation, terrorist outfits, mainly Babbar Khalsa International and and Khalistan Commando Force, have tried to bring in youths from other states and countries for terror activities in Punjab.
BKI's Jagtar Singh Hawara, who escaped from a Chandigarh prison in January 2004, tried to revive terrorism but failed. He was later arrested by Delhi Police from Patiala.
When the Khalistan campaign raged for a decade until 1993, over 25,000 people were killed. The last big terrorist strike was the assassination of then Punjab Chief Minister Beant Singh in Chandigarh Aug 31, 1995.
