Pakistan’s civil aviation authority is reported to have shut its airspace to all commercial flights due to escalating tensions with India.

The move follows India announcing restrictions on its airspace.

The airline Vistara said flights in the region were being suspended.

Pakistan has stopped flights from at least five airports including Islamabad and Lahore.

Flight monitoring group Flight Radar says international flights are also avoiding the area.

This comes as two Indian air force jets were said by Pakistan to have been shot down in the dispute over Kashmir.

Pakistan previously denied reports tat one of its aircraft was downed.

The aerial attacks across the Line of Control dividing Indian and Pakistani territory are the first since a war in 1971.

They follow a militant attack in Kashmir which killed 40 Indian troops. A Pakistan-based group claimed responsibility.
