They said IAF's AWACS picked up signals of presence of an F-16 aircraft when Wing Commander Abhinandan Varthaman's MiG-21 Bison was engaging with the enemy jet.
Taking to Twitter, Imran Khan said, "BJP's attempt to win elections through whipping up war hysteria and false claims of downing a Pak F 16 has backfired with US Defence officials also confirming that no F16 was missing from Pakistan's fleet". It did not identify the officers.
Pakistan has denied that it lost any F-16 jet during the aerial combat.
Addressing the press conference in Vadodara, she said that the writers of the article should do proper study of the "technical and factual" evidences provided by the Indian Air Force to concretely prove the use of F-16 by Pakistan to target the Indian military installations.
The aerial clash over Kashmir followed an Indian air strike on what New Delhi said was a terrorist training facility inside Pakistani territory. The two nations previously have fought four wars, in 1947, 1965, 1971 and a limited conflict in 1999.
The count, conducted by United States authorities on the ground in Pakistan, casts doubt on India's version of events, suggesting that Indian authorities may have misled the global community about what happened that day, it adds.
There was no Indian or US official reaction to the report.

When it comes to Instagram , it seems no-one can match the allure of a youthful royal couple expecting their first child . The Duke and Duchess of Sussex have been hard at work preparing for the arrival of their first royal baby this spring.
Pakistan Air Force (PAF)'s fighter jet F-16 flies during an air show to celebrate the country's Independence Day in Karachi, Pakistan August 14, 2017. Pakistan had officially announced about two aircraft going down but later retracted, saying only one (the Indian) jet was hit.
According to IAF sources, the Army witnessed the first parachute - that of Wing Commander Varthaman as he ejected after his Mig-21 was shot down - coming down in General Area Sabzkot where he was captured by the 7 Northern Light Infantry (NLI) of he Pakistan Army.
They said, Indian ground forces also sighted two parachutes coming down at Sabi Kot and Tandar following the aerial combat on February 27. Pakistani officials, as well as the locals, rejected the claims, inviting local and global media to visit the site of the so-called attack where around a dozen trees were the only "casualty".
When the incident occurred, India asked the USA government to investigate whether Pakistan's use of the F-16 against India violated the terms of the foreign military sale agreements. It attributed the finding to two unidentified senior United States defence officials and said the count was conducted at the invitation of Pakistan.
Pakistan offered to open one air route on Friday, an Indian government official said, without specifying details and declining to be named as the matter was not public.
