A rescue diver in the Maldives searching for the bodies of four Italians, who drowned in the deadliest diving disaster in the Indian Ocean tourist destination, has also died, authorities said.
Teams from the Maldivian National Defence Force (MNDF) were searching for a third day for the Italians who failed to return after a dive on Thursday, officials said.
One body from the group of five was recovered the same day.
Search operations were being carried out despite bad weather.
Earlier, the Maldives suspended the operating licence of a luxury vessel from which the Italians had been diving from.
The University of Genoa said the victims included a marine biology professor, her daughter and two young researchers.
A Maldives government spokesman said an investigation had been launched into why the group went below the officially permitted depth of 30 metres.
The body of one diver, yet to be publicly named, was found in a cave at a depth of 60m.
"The Ministry of Tourism and Civil Aviation has suspended the operating licence of the liveaboard vessel MV Duke of York indefinitely, pending the outcome of an investigation into the diving incident that occurred in Vaavu Atoll on May 14," the ministry said.
The Duke of York is a 36m luxury boat that can accommodate 25 guests.
Italy's foreign ministry confirmed on Thursday that all five of its nationals had died.
The low-lying Maldives, a nation of 1,192 tiny coral islands scattered some 800km across the equator in the Indian Ocean, is a luxury holiday destination popular with divers, who often stay at secluded resorts or on liveaboard dive boats.
Diving and water-sport-related accidents are relatively rare in the South Asian nation, although several fatal incidents have been reported in recent years.
