Islamabad: A Counter-Terrorism Department (CTD) of Pakistan police on Friday registered a First-Information Report (FIR) against the alleged attackers of the Pathankot airbase in India and their abettors.
FIR number 06/2016 was registered in the CTD police station Gujranwala in Punjab province, a CTD spokesman said.
A formal investigation was launched following the registration of the FIR, he said, adding that a joint investigation team will probe the attack and those involved will be brought to trial in accordance with law, Dawn online reported.
According to the FIR, Indian National Security Adviser (NSA) Ajit Doval informed authorities that the four attackers had come from Pakistan and had "probably crossed the border adjacent to the Pathankot general area".
The NSA is cited as saying that while in India, they made phone calls to cell phones and belonged to a proscribed organisation.
The attack occurred on January 2, when a heavily armed group attacked the Pathankot Air Force Station, part of the Western Air Command of the Indian Air Force. A total of 14 people were killed - six attackers, seven security personnel and one civilian.
The gun battle lasted for 17 hours.
