Radar images of an air battle between Indian Air Force (IAF) pilot Abhinandan Varthaman and a Pakistani jet during a February dogfight were shown by the air force today as "irrefutable proof" that a Pakistani F-16 fighter jet had been shot down by India. Last week, American news publication Foreign Policy had contradicted India quoting unnamed US defence officials as saying that Islamabad's F-16s were counted and "none were missing."
