Questions are being asked in India after a popular foot bridge collapsed, plunging scores of pedestrians into a river in the western state of Gujarat.

The horror in the town of Morbi on Sunday evening is one of the worst tragedies in India for years, killing 135 people, most of them women, children and the elderly.

The 137-year-old suspension bridge had reopened just five days earlier following repairs - so what went wrong?

The BBC spoke to survivors, first responders, local journalists and officials to piece together a story of needless tragedy.

Local residents and journalists blame the company which operated the bridge - and the police and local authorities are also accused of failures.

Just after 18:30 (13:00 GMT) on Sunday, Mahesh Chavda and two of his friends bought their tickets and stepped onto Morbi's swaying 'jhulto pul' (hanging bridge).

It's described by the state's tourism website as a "technological marvel" and is popular with sightseers - it had been Mahesh's favourite go-to place ever since he'd been a child.

Spanning the Machchu river, the 230m (754ft)-long structure connects Darbargarh Palace and Lakhdhirji Engineering College. Dates for its construction vary, but locals say it was built in the 1880s by the local Maharaja, Waghji Thakore.

"I used to visit it with my parents and, for the past few years, I'd go there every Sunday with my friends," says Mahesh.

He was "excited" when he heard last week that the bridge had reopened and the 18-year-old and his friends decided to resume their Sunday evening routine.

Sitting on his hospital bed with plaster around his neck, Mahesh told me that as they approached the bridge, they could see that it was overcrowded.
