Five tourists have died in a scuba diving accident in the Maldives.

The group,from Italy,had been exploring underwater caves in the Vaavu Atoll at a depth of around 50 metres on Thursday.

Four of the divers were part of a team from the University of Genoa,her daughter and two researchers.

It is believed to be the worst single diving accident the South Asian nation – popular with sightseers thanks to its vibrant coral reef system – has seen.

Italy’s foreign ministry did not give ‌any ⁠details about the exact cause of ​the ​accident.

The five divers – named as Ms Montefalcone,her daughter Giorgia Sommacal,20,research fellow Muriel Oddenino,marine biology graduate Federico Gualtieri,and boat operations manager and diving instructor Gianluca Benedetti – entered the water on Thursday morning,local reports said.
