Union Home Minister Rajnath Singh today came down heavily on Pakistan saying if the neighbouring country does not allow a National Investigation Agency team to visit there for probe into the attack on the Pathankot airbase, it would be a 'betrayal' to India.

Singh also said that Jammu and Kashmir has never been an issue between India and Pakistan and if there is an issue between the two countries, it is the issue of Pakistan-occupied Kashmir.

Addressing a gathering of prominent persons and intellectuals, the home minister said when the Joint Investigation Team of Pakistan proposed to visit India for investigating the Pathankot terror attack case, it was mutually agreed that after the visit of the Pakistani investigators to India, a team of the NIA would also visit the neighbouring country for probe and interrogate some people.

"But so far Pakistan has not given permission to the NIA to visit there. If the NIA team is not allowed to visit Pakistan, it will be a betrayal to India," he said.
