The bodies of 15 tourists who drowned in a speedboat accident in Vietnam on Saturday afternoon have been returned to India.

The vessel was ferrying 32 Indian tourists and four Vietnamese crew members when it capsized, shortly after departing Hon May Rut Ngoai island, authorities said.

The bodies were flown from Ho Chi Minh City to Mumbai on Monday, the Indian embassy in Vietnam posted on X. The embassy said earlier that 16 survivors had been discharged from a local hospital and were returning to India. All the deceased were from the south of the country.

The boat overturned within minutes of departure when a large wave hit it, AP reported. The boat swerved in rough waters before it capsized. Rescue teams arrived within five minutes and pulled survivors from the water.

One survivor, who is in critical condition, has been transferred to Cho Ray Hospital in Ho Chi Minh City for specialized treatment.

The tourist group was on a trip organized by a smartphone manufacturer for its employees, distributors, and retail partners.

The accident occurred about 6 miles south of Phu Quoc, Vietnam’s largest island and one of its most popular beach destinations, which attracts millions of domestic and foreign tourists each year.
