At least 14 people have been killed after a flyover under construction collapsed in Kolkata (Calcutta), India.
Initial reports from officials in the eastern Indian city suggest that up to 150 people could be trapped under the concrete and steel bridge.
The 2km (1.2 mile) flyover has been under construction since 2009.
The structure appears to have hit passers-by, cars, lorries and buildings, with people said to be living in makeshift homes under the flyover.
Construction projects in India have often suffered from safety issues with frequent collapses. Experts say there is a lack of inspections and substandard materials are used.
The accident took place in an area near Girish Park, one of Kolkata’s most densely populated neighbourhoods, with narrow lanes, and shops and houses built close together.
Ramesh Kejriwal, an eyewitness, said: “There was a loud sound which scared us. The concrete had been laid last night at this part of the bridge.”
At least 60 people have been taken to nearby hospitals, with some of them said to be in a critical condition.
Emergency teams have been sent to the area with sniffer dogs, concrete cutters, drilling machines and sensors to detect life, he added.
