MALÉ, Maldives — A dream excursion into the crystal-clear waters of the Indian Ocean has culminated in what local authorities are calling the deadliest single diving accident in the history of the Maldives. Five Italian scuba divers lost their lives on Thursday, May 14, 2026, after becoming trapped inside a deep, complex underwater cave system in the Vaavu Atoll.

The disaster has sent shockwaves through Italy’s scientific and academic communities, as four of the five victims were closely affiliated with the University of Genoa.

The victims were part of a larger expedition traveling aboard the Duke of York, a 36-meter luxury liveaboard dive boat catering to technical and deep-sea divers. The group entered the water on Thursday morning near Devana Kandu—a channel near Alimathaa Island, roughly 100 kilometers south of the capital city of Malé.

The dive targeted a notoriously challenging cave system with an entrance resting between 55 and 58 meters below the surface. While the Maldives imposes an official recreational diving depth limit of 30 meters, the Duke of York frequently accommodates certified technical and rebreather divers equipped for extreme depths. Local experts emphasize that the cave system—which branches out into three large chambers connected by narrow passages—extends past 60 meters deep and requires rigorous technical training.

Alarm bells rang at 1:45 p.m. when the five divers failed to resurface by midday. The Maldives National Defence Force (MNDF) Coast Guard immediately deployed speedboats and aerial support to initiate a high-risk search and rescue operation.

At 6:13 p.m. on Thursday, rescue teams recovered the first and only body found so far: 44-year-old Gianluca Benedetti, an experienced diving instructor and boat operations manager for the cruise operator. His body was located near the mouth of the cave system. Authorities believe the remaining four divers pushed deeper into the labyrinth and remain trapped within the cave’s innermost chambers.

On Friday, the University of Genoa released a somber statement identifying the other four victims from its heavily impacted marine sciences department. The deceased include 51-year-old Monica Montefalcone, an associate professor of ecology and renowned marine biologist specializing in seagrass and coral ecosystems, alongside her daughter, Giorgia Sommacal (22/23), a biomedical engineering student at the university.

The tragedy also claimed the lives of 31-year-old marine biology research fellow Muriel Oddenino and Federico Gualtieri (31), a certified diving instructor and recent marine biology graduate who had just completed his thesis on Maldivian corals under Professor Montefalcone's supervision.

Montefalcone’s husband, Carlo Sommacal, publicly defended his wife's technical proficiency, stating to Italian media that she was an incredibly disciplined, risk-conscious diver and that "something unexpected must have occurred".

A yellow weather warning was active in the region on the day of the dive, bringing rough seas, low visibility, and powerful channel currents. These adverse weather conditions severely hampered the initial response and forced authorities to temporarily suspend recovery operations on Friday.

Maldivian presidential spokesperson Mohamed Hussain Shareef confirmed that eight specialized rescue divers worked in pairs to explore the first two chambers of the cave, managing to map out the interior before being turned back by the deteriorating weather. Two top Italian deep-sea rescue and cave-diving experts are flying into Malé to assist local teams in navigating the dangerous third chamber.

Meanwhile, Italy's Foreign Ministry confirmed that the remaining 20 Italian nationals who were aboard the Duke of York are safe. The vessel has sought safe harbor from the storm, and the Red Crescent has volunteered to provide psychological first aid to those on board.

As the Maldivian police and international diving safety organizations launch a thorough investigation, hypotheses regarding the cause of death—including oxygen toxicity or catastrophic gas mixture failure—remain entirely speculative. Recovery operations are scheduled to resume as soon as sea conditions improve.
