Pakistan's ISI is learnt to have launched 'Project Harvest' against India, which is aimed at targeting senior retired police and Army officers in Punjab and other parts of India.

India Today TV has learnt that ISI has launched 'Project Harvest' to start a drive to target retired police officials and army personnel. Sources say a Canada-based Khalistan activist has been given the responsibility to launch 'Project Harvest'.

Security agencies are also keeping an eye on the activities of pro-Khalistan group 'Sikhs For Justice' (SFJ), which is sponsoring free air tickets to people willing to join the Khalistan Referendum movement. The agencies are also investigating whether SFJ was part of ISI's 'Project Harvest'.

Meanwhile, the Station Superintendent at Pathankot Railway Station has received a threat mail claiming the Pathankot City and Cantt railway stations will be blown up. Police said the letter was received by post.

Security has been heightened in Pathankot while forces are also bracing for ISI trying to flare separatist activities and tension in the Punjab region.

Highly placed sources told India Today TV that fake news on the dismantling of Guru Nanak Mahal structure could also be the brainchild of ISI to instigate Sikhs.

Punjab Chief Minister Captain Amarinder Singh had expressed apprehension that Pakistan's ISI and hardline Sikh groups may misuse Kartarpur corridor for anti-India activities.

While Prime Minister Narendra Modi has made it clear that India will not tolerate any separatist activities, Pakistan PM Imran Khan is under pressure to act against Khalistan and other terror groups. However, action may be limited to issuing statements as ISI continues to oppose the moves.

It is to be noted here that the differences between Imran Khan and Pakistan Army Chief General Qamar Bajwa are growing over pro-India and pro-Sikh initiatives like opening of the Kartarpur corridor.
