India Kolkata flyover collapse: At least 20 dead

A flyover under construction in the Indian city of Kolkata (Calcutta) has collapsed, killing at least 20 people and injuring nearly 100.

A number of people are feared trapped under the concrete and steel bridge, which fell on a busy road.
Safety issues such as lack of inspections and the use of substandard materials have plagued construction projects in the country.
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.
The 2km-long (1.2 mile) flyover had been under construction since 2009 and missed several deadlines for completion.
