At least 32 people were feared dead after a 100-year-old suspension bridge collapsed in India on Sunday, local media reported.

More than 350 people were on the Morbi bridge, in the western state of Gujarat, when it collapsed, media quoted officials as saying.

The Press Trust of India reported the death toll as being at least 32, citing local health officials.

Harsh Sanghavi, Gujarat's home minister, however, put the death toll at seven.

The British-era suspension bridge was only reopened to the public this week, after months of repairs.

Authorities launched a rescue operation following the collapse, with divers deployed to search for missing people.

Prime Minister Narendra Modi, who was touring his home state of Gujarat, announced compensation for those killed and injured in the accident.

Modi "sought urgent mobilisation of teams for rescue (operations)", his office tweeted.

"He has asked that the situation be closely and continuously monitored, and (for authorities to) extend all possible help to those affected."
