Ludhiana | Rescue operation was underway Sunday to see if anyone was still trapped under the debris, a day after a factory building collapsed here.

A worker was killed after a building of a textile factory collapsed in the Focal Point area here late Saturday evening, officials said.

The six workers trapped under the debris were brought out by the NDRF teams, of which one was found dead and three sustained serious injuries.
