At least 24 people have died in Kolkata and 75 have been injured in the collapse on Thursday of a flyover under construction in a crowded commercial area. Rescuers worked through the night with cranes, saws and jackhammers to look for those trapped in debris.
Here are 10 developments in the story:
- Around 90 people were saved after a 100-metre length of the flyover came crashing down on pedestrians and vehicles on a road in Burrabazaar, one of the city's oldest and busiest areas.
- CCTV visuals showed the moment when the bridge suddenly collapsed on moving traffic during lunchtime, crushing pedestrians, cars and other vehicles under huge concrete slabs and metal.
- "The rescue operation is in the final stages. Chances of finding survivors are low," said an official for the National Disaster Response Force.
- Most suffered multiple fractures and are in a critical condition, Mr Shekhawat said, adding that an unknown number of people still trapped under the wreckage.
- Army and disaster response personnel sifted through the rubble overnight armed with concrete and metal cutters, drilling machines and heat sensors to detect life.
- But three cranes working overnight managed to clear some of the wreckage and free access to vehicles with people still believed to be trapped inside.
- Hyderabad-based IVRCL group, which was contracted to build the flyover, called its collapse an "act of God". Its office has been sealed and a case has been registered against the company.
- The 2 km bridge has been under construction since 2009 and has missed several deadlines for completion.
- The company was given an 18-month deadline and a budget of nearly Rs. 165 crore to complete the project in 2009, but after seven years only about 60 percent of the work has been done.
- Chief Minister Mamata Banerjee said those responsible for the disaster would not be spared and blamed the previous Left government that had awarded the flyover contract in 2007.
