A diver has died while searching for the bodies of a group of Italians who perished during a deep-sea cave expedition in the Maldives.

Italy’s Foreign Ministry said the five divers “apparently died while attempting to explore caves at a depth of 50 meters (164 feet)” in the Vaavu Atoll on Thursday.

Rescue teams in the Maldives continued recovery operations after the country’s deadliest diving accident killed five Italian divers.
