A Maldivian military diver died while searching for four Italian divers missing in an underwater cave in Vaavu Atoll.

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.

The divers became trapped in a sea cave at a depth of about 50 metres. A high-risk search for the bodies was suspended because of rough seas.
