At least 100 hutments in a slum at Gurugram's Basai Chowk area were gutted on Saturday, an official said.
The fire broke out at 6 am, the official said.
"Soon after the Fire Department received a call, fire tenders from different stations were pressed into service to douse the flames, which erupted in a hut," an official of the Fire Department said. The exact cause of the fire was yet to be ascertained.
"Firefighters managed to douse flames within a few hours, and nobody was injured in the incident," the official added.
Gulsan Kalra, Deputy Director of the Fire Department, said: "We have written to the concerned departments on several occasions to remove such encroachments in Gurugram so that we can curb the fire incidents."
