22 dead in India building collapse

NEW DELHI, June 29 (agencies): Police in southern India detained two construction company directors Sunday as rescuers using gas cutters and shovels searched for dozens of workers believed buried in the rubble of a building that collapsed during monsoon rains. It was one of two weekend building collapses that killed at least 22 people.   The 11-story apartment structure the workers were building collapsed late Saturday while heavy rains and lightning were pounding the outskirts of Chennai, the capital of Tamil Nadu state.
The accident late Saturday was India's second deadly building collapse in one day, after a dilapidated apartment block crumbled in the capital New Delhi, killing ten people including five children.
The partly-built tower, about 20 kilometres (10 miles) from Chennai in Tamil Nadu state, crushed mostly labourers at the site who had gone inside it to shelter from the rain.
Senior police officer Karuna Sagar told AFP that 11 bodies had been pulled from the wreckage as of Sunday afternoon while 20 people had been rescued and were being treated in hospital.
He said police had detained several people for questioning, including the builder and construction engineers.
Sagar said witnesses had described hearing a loud bang, with the building collapsing after around 50 workers went inside it to seek shelter.
He said dozens may still be trapped.
TV and still footage showed crowds of yellow-helmeted rescuers searching the ruins-huge slabs of concrete which had pancaked onto each other, twisted steel reinforcing rods and tangled scaffolding.
Rescuers sifted through the debris with shovels as they searched for trapped survivors.
Dust-caked bodies of the dead and injured were carried out on stretchers as rescuers struggled to make their way through mounds of rubble.
A disaster management official leading the search called the operation a "big challenge" and said clearing the debris could take a few days.
"There is no clarity on the number of people trapped," S. P. Selvan, a senior officer from the National Disaster Response Force, told reporters in Chennai, according to the Press Trust of India.
Building collapses are common in India. Lax regulations and the demand for cheap housing mean contractors sometimes use substandard materials or add unauthorised extra floors.
