"On 27 Feb, our air defence system was on full alert," the IAF said in a statement released Tuesday.
It added that the build up of Pakistani aircraft was noticed in time and Indian aircraft scrambled.
The IAF statement said India scrambled Mirage-2000s, Su-30s, and MiG-21 Bisons and that consequently, the "PAF aircraft were forced to withdraw in hurry".
It added that that was "also evident from large missed distances of weapons dropped by them".
Indian Air Force statement: Detailed report in this regard has already been released by IAF. All the Su-30 aircraft engaged in combat landed back safely. False claim by Pakistan of shooting down a Su-30, appears to be a cover up for loss of its own aircraft. https://t.co/Ccd04mX53G
"During combat, use of F-16 by PAF and multiple launches of AMRAAM were conclusively observed," the IAF said Tuesday.
India has taken up Pakistan's use of the F-16s and of the AMRAAM missiles fitted on them with the US. Their use by Pakistan may violate its end-user agreement with the US since the American-supplied jets and missiles are reportedly supposed to be used only in counter-insurgency operations.
"All the Su-30 aircraft engaged in combat (on Feb 27) landed back safely. False claim by Pakistan of shooting down a Su-30 appears to be a cover-up for loss of its own aircraft," the Indian Air Force said in a statement.
