NEW DELHI (AP) — Police say rescuers have pulled more than a dozen survivors from under the concrete ruins of a collapsed 11-story building three days after it toppled and killed at least 29 people in southern India.

Already, 55 people have been rescued from the enormous heap of broken slabs, twisted iron girders and concrete dust where the apartment building was being constructed in a suburb of Chennai, the south-coast capital of Tamil Nadu state.

Hundreds of rescue workers are likely to continue searching for survivors for at least another day. They also expected to find more bodies, as rescuers said the foul smell of death had become overpowering on Tuesday.
