Canada / Punjab, June 03: Few months after the Pathankot terror attack, Indian intelligence agencies have sent an alert to the Canadian government, saying that pro-Khalistan terrorists are running a camp in British Columbia. According to a report prepared by Punjab intelligence sleuths, Canadian Sikh Hardeep Nijjar has taken over as the operational head of Khalistan Terror Force (KTF) and formed a module comprising Sikh youths to carry out attacks in Punjab. The Punjab government has already submitted the report to the ministries of external affairs and home affairs to seek Nijjar's extradition. Meanwhile, Punjab police has apprehended an operative of Sikh separatist group Babbar Khalsa International on May 26. A resident of Chak Kalan village, Mandeep Singh, had recently returned from Canada where he underwent armed training. Sikh separatists spearheaded a campaign for the formation of Khalistan, an independent Sikh state in the 1980s which continued till early 90s. Terrorism in Punjab was at its peak during that period. A decade of separatist violence in Punjab claimed over 15,000 lives.
