Indian Defense Minister Manohar Parrikar said on Tuesday that the militants could not have carried out the brazen attack on the heavily-guarded base near the Pakistan border without Islamabad's support.
The minister also noted that National Investigation Agency (NIA), a federal police unit that investigates terror offences, is carrying out a probe into the case.
"Pakistan's non-state actors were definitely behind the attack. Also, no non-state actor from there (Pakistan) can function smoothly without the state's support," Parrikar told parliament in New Delhi, adding, "The entire details of the attack will only come out in the National Investigation Agency (NIA) investigation."
India has blamed militants from the Pakistan-based Jaish-e-Mohammed militant group for the assault on the site in Pathankot district, which is located about 50 kilometers (30 miles) from the Pakistan border.
