Five people died when a tourist hovercraft capsized on Lake Baikal in Siberia, Russian emergency officials reported.

The vessel, identified as a Sever-750 airboat designed to operate on both ice and water, was carrying 18 people when it overturned just offshore. The remaining 13 passengers survived the accident.

The hovercraft was operating as a tourist vessel on the lake when the incident occurred. Lake Baikal, located in southern Siberia, is the world's deepest freshwater lake and a popular tourist destination.

Russian authorities have launched an investigation into the circumstances surrounding the deadly accident. The cause of the capsizing has not been determined.

The Sever-750 is a type of airboat specifically engineered to travel across various surfaces including ice and water, making it suitable for the conditions found on Lake Baikal during different seasons.
