Divers have found two more bodies after a duck boat carrying tourists capsized in south-west Missouri, bringing the death toll to 13.

Four others remain missing after the accident on Table Rock Lake in the city of Branson on Thursday evening, amid stormy conditions.

Missouri State Highway Patrol Sgt Jason Pace said 14 others survived, with seven of these having been injured.

The officer said those who died ranged in age from just one to 70 years old.

Branson is about 200 miles south-east of Kansas City and is a popular vacation spot for families and other tourists looking for entertainment ranging from theme parks to live music.

Duck boats can operate on both land and water, were initially used by the US military before being converted for use as tourist vehicles. The boats have been involved in several deadly incidents in the past.

Five college students were killed in 2015 in Seattle when a duck boat collided with a bus, while 13 people died in 1999 when a duck boat sank near Hot Springs, Arkansas.
