ITANAGAR, March 14 – A forest fire has been raging in the Dariya Hills in Arunachal Pradesh for the last three days with black smoke bellowing into the sky of the State capital threatening the flora and fauna here. “It appears to be a daunting task to douse the fire in Dariya Hills, which comes under Itanagar Wildlife Sanctuary, as the State does not have required resources to tackle such massive bushfire going on for three days”, Forest department sources said.
