The investigation into the drone strike at Air Force Station Jammu has been handed over to the National Intelligence Agency (NIA), sources in the Ministry of Home Affairs told India Today. The development comes after the elite counter-terrorism unit submitted a preliminary report of the incident to the ministry.

The NIA is expected to lodge a case to begin the probe officially.

It is suspected that a Pakistan-based terror group was behind the attack on the Jammu air base. The Ministry of Home Affairs has been keeping a close eye on the developments in the case, a government source said.
