An Indian Air Force helicopter had to make an emergency landing at a forested location in Chhattisgarh Friday evening after Maoist rebels opened fire on it, police said. The crew, one of whom was injured, safely reached a nearby paramilitary camp.

Officers at the police headquarters here said that Mi-17 chopper, which took off from Jagdalpur town to Sukma district to airlift some troopers seriously injured in a gunfight with Maoists, went missing after rebels attacked it.
