NEW DELHI : Rescuers have pulled 13 more bodies from the rubble of a building that collapsed last weekend in southern India, raising the death toll to at least 55, officials said Thursday. The 11-storey apartment tower on the outskirts of Tamil Nadu’s state capital Chennai, which was still under construction, came crashing down Saturday following heavy rains, killing mainly labourers. Karuna Sagar, a senior officer with the Tamil Nadu state police force, said the confirmed death toll from the disaster now stood at 55 and added that chances of finding more survivors “appear bleak”. Some 27 people have been rescued from the rubble so far. It is not known how many people were inside the building at the time of the collapse.
