A chartered aircraft flying from Muscat to Dhaka entered the restricted airspace over Jodhpur airbase and has been grounded by authorities at the Sanganer Airport in Jaipur.

"The aircraft piloted by Captain Ibrahim Hun flew over Jodhpur airforce area without permission before scheduled landing at the Sanganer Airport in Jaipur for refuelling last evening," official sources said on Monday.

"The aircraft deviated from its scheduled route but it was being monitored. We got information from Delhi ATC about the violation so the pilot was questioned and the matter is being examined," they said.

Intelligence agencies were also informed and the aircraft will be allowed to take off only after clearance from DGCA, they said. According to the pilot, the aircraft deviated from the route because of some technical problem in the GPS system.
