India has taken Pakistan to global civil aviation body International Civil Aviation Organization (ICAO) for denying the use of airspace for transit for President Ram Nath Kovind and Prime Minister Narendra Modi.

Islamabad on Sunday announced that it will not be allowing the use of its airspace for PM Modi's plane during his visit to Saudi Arabia.

Reacting to the development, a government source said, "We regret the decision of the Government of Pakistan to yet again deny overflight clearance for the VVIP special flight, which is otherwise granted routinely by any normal country."

Explaining, "Overflight clearances are sought, and granted by other countries as per prescribed ICAO guidelines and India will continue to seek such overflight clearances. Separately, we have taken up the matter of such denial with the relevant international civil aviation body."

Under the charter of ICAO, unless it's war, denying the use of airspace by singling out cannot be done by any country. Pakistan can be slapped with a heavy fine.

This is the second time since the abrogation of Article 370, Pakistan has denied the use of its Airspace for PM Modi. Pakistan denied airspace when Modi was travelling to New York for United Nations General Assembly week in September.

"Pakistan should reflect upon its decision to deviate from well established international practice, as well as reconsider its old habit of misrepresenting the reasons for taking unilateral action," a government source said.

Pakistan has also denied the use of its airspace for President Ram Nath Kovind's plane in early September.

Pakistan had closed its airspace on February 27 after India's counter-terror operation in Balakot on February 26 following Pulwama attack that killed more than 40 Indian security personnel.

The closure that lasted for more than four months had caused a considerable problem for air travellers across the globe.
