Pakistani officials today alleged that two Indian fighter jets entered seven kilometres into the country's airspace over Punjab province.
They said the incident occurred over Pakpattan district, 200-km from the provincial capital of Lahore.
The officials alleged the jets remained in Pakistani airspace for over one minute.
IAF sources in Delhi, however, rejected the claim saying, "Our pilots did not cross the border".
An official from Pakistan's Civil Aviation Authority told PTI that the Indian jets violated Pakistani airspace over Head Sulemanki area of Pakpattan district.
"The two jets entered some seven kilometres inside Pakistani airspace. After remaining for over one minute in Pakistani airspace, they left," said the official, who did not want to be name.
Pakistan has not yet officially registered a protest with India over the incident, officials said.
The incident occurred at about 10.40 am, Geo News channel reported. It said the Pakistan Air Force had scrambled its fighter jets following the intrusion though this could not be independently confirmed.
