Rescuers are still digging through the rubble of a decades-old four-storey building in south Mumbai's crowded Dongri area that collapsed on Tuesday morning. Fourteen people were killed and over 40 were feared trapped. Nine people - including two children - have been rescued. Three teams of the National Disaster Response Force, joined by residents of the south Mumbai neighbourhood where several old buildings stand cheek by jowl, worked through the night to remove blocks of broken concrete and bricks using portable power tools.
