All six people on board an Indian Air Force Mi-17 helicopter escaped unhurt after it caught fire on Tuesday after flying into an iron girder near Kedarnath temple in Uttarakhand, PTI reported.

The helicopter, which was on an air maintenance mission, was carrying three crew members and four labourers, The Indian Express reported. It was carrying construction material from Guptkashi to Kedarnath. The crash took place when the Russian-made Mi-17 helicopter was landing at a helipad near the temple.

“Just 20 metres before the helipad in Kedarnath, the Mi-17 helicopter, which was flying low, collided with a cable and crashed,” Rudraprayag Superintendent of Police Prahlad Meena said, according to The Indian Express.

A Court of Inquiry will be conducted to ascertain the cause of crash, authorities said.
