Exclusive: US says its main focus is to reduce tensions between India and Pakistan 

As part of the purchasing agreement, the US had reportedly barred Pakistan from using the F-16s against any third country and it was only allowed to operate in self-defence and for anti-terror missions.

The Indian Air Force on February 28 displayed parts of an AMRAAM missile as evidence to "conclusively" prove that Pakistan deployed US-manufactured F-16 fighter jets during an aerial raid targeting Indian military installations in Kashmir. It said Pakistan does not have any other fighters capable of firing an AMRAAM missile.

“There are eye-witness accounts and electronic evidence that Pakistan deployed F-16 aircraft and that one F-16 was shot down by Wing Commander Abhinandan. Evidence of the use of AMRAAM Missile, which can only be deployed on the F-16 with Pakistan, has also been shown to the media. Pakistan should explain why it continues to deny that its F-16 aircraft has been shot down”, the Ministry of External Affairs, in a statement, had said.

Pakistan has categorically said that no F-16 fighter jets were used in the aerial combat against India.

The Indian government had officially asked the United States to examine whether the use of F-16s against India is a violation of the terms and conditions of sale between US and Pakistan but Pentagon has refused to confirm.

“Due to contractual non-disclosure agreements, we cannot talk about end-user agreements associated with foreign military equipment (FMS) sales”, the spokesperson said.

The spokesperson for the US Embassy also refused to comment on the F16 agreement with Pakistan and whether the US could take action against the country for violating the agreement.

“As a matter of policy, we do not publicly comment on the contents of bilateral agreements involving US defence technologies nor the communications we have about them”, the US Embassy spokesperson told CNBC-TV18.

Both the Pentagon and the US Embassy did not comment on whether an F16 belonging to the Pakistan Air Force was shot down by the India Air Force on February 27.

India has been in close communication with the United States ever since the attack on a CRPF convoy in Pulwama, Jammu and Kashmir on February 14.
