In response to the threat made by Khalistani separatist Gurpatwant Singh Pannun regarding Air India flights, the Indian government has implemented enhanced security measures at airports in Delhi and Punjab to mitigate potential security risks. The Bureau of Civil Aviation Security has mandated additional security checks for Air India flights in these regions, requiring passengers to undergo a "secondary ladder point check." As part of these measures, the sale of visitor entry tickets and entry of visitors to the terminal building at Delhi's IGI Airport will be suspended until November 30. This move comes after Gurpatwant Singh Pannun, a designated terrorist and the founder of the banned Sikhs for Justice (SFJ), released a video urging Sikhs not to fly on Air India aircraft after November 19, citing potential threats to their safety. This threat has emerged against the backdrop of deteriorating diplomatic relations between India and Canada. The strain began when Canadian Prime Minister Justin Trudeau made allegations implicating the "Indian government" in the killing of Nijjar. India categorically rejected these allegations as "absurd and motivated" and responded by expelling a Canadian diplomat in a tit-for-tat action. However, Canada has not provided any public evidence to substantiate the claim regarding Nijjar's killing.
