The BJP government has stabbed "Mother India" in the back by allowing Pakistan's Inter-Services Intelligence (ISI) inside the country to probe the Pathankot attack, Delhi Chief Minister Arvind Kejriwal said on Tuesday."Even though BJP/RSS chants 'Bharat Mata ki Jai,' but by inviting ISI to India they have stabbed Mother India in the back," Kejriwal tweeted in Hindi. The government allowed a Joint Investigation Team (JIT) from Pakistan, including an ISI official, to visit India last month to probe the terrorist attack in January on Pathankot air force station in Punjab. The JIT has concluded, according to media reports in Pakistan, that the Pathankot attack was staged by India to spread "viciuos propaganda" against Pakistan. "It is very shameful. It is for the first time that any Prime Minister has insulted the country before Pakistan," Kejriwal said in another tweet. Kejriwal's Aam Aadmi Party (AAP) has been protesting against allowing Pakistan's JIT a role in the investigation on the ground that the ISI, a state actor, has long been the instigator of terrorism in India.
