"Wreckage found. Close to the last known position of aircraft".
The remains have been found 60 km northwest of Tezpur city in Sonitpur district of India's northeastern state of Assam. The debris is yet to be retrieved as bad weather and dense foliage has hampered operations, the PRO said. Two pilots were on-board the aircraft.
The Su-30 jet had gone off the radar and lost radio contact around 1110 hours on Tuesday when aircraft was around 60 km from Tezpur. "Army search teams are also attempting to reach the site by trekking cross country but their progress is being hampered by inclement weather, thick vegetation and steep gradient of the terrain", said an IAF officer on Friday.
The Indian Air Force has also ordered a court of inquiry to ascertain the cause of the accident of the aircraft which vanished after losing radar contact within 40 minutes of taking off.
Search and Rescue operations have been activated to locate the aircraft and the pilots.
Since then, six crashes have taken place.
The statement said ground parties were to be airlifted to the crash site as the area is totally inaccessible.
SU-30 MKI was inducted in the Tezpur air base during the tenure of former IAF Vice Chief Air Marshal P K Barbora on June 15, 2009.
China's Foreign Ministry spokesperson Lu Kang on Wednesday said in Beijing that he had "no relevant information" on the missing jet.
In March this year a Sukhoi crashed in Rajasthan's Barmer.
