A fire swept through a shantytown Friday morning, sending huge plumes of black smoke rising over the Indian capital.

Twenty fire trucks, with a total of 70 firefighters, were still battling to put the flames out a few hours after the fire was reported, but fire department chief A.K. Sharma said the blaze was no longer in danger of spreading.

No injuries or deaths have been reported yet, he said.

The fire is next to a row of three hospitals in Delhi, the historical part of the Indian capital, but a brick wall separating the two areas has kept the hospitals safe, Sharma said.

The black smoke was coming from burning materials including plastic tarps and bottles, tires and scraps of wood that had been collected by the slum's thousands of residents who work collecting garbage for resale.

Another fire a day earlier in the nation's financial center of Mumbai gutted state government offices and killed three people before authorities could put it out.
