WASHINGTON: A tourist boat capsized and sank Thursday during a fierce storm on a lake in Missouri, killing at least eight people, the local sheriff said.

Another seven people were hospitalized and an unknown number were missing after the accident on Table Rock Lake, Stone County Sheriff Doug Rader told a news conference.

Divers are in the water looking for people, he said.

He said 31 people had been aboard the vessel, known as a duck boat because it has wheels that allow it to ride on land as well.

The man-made lake is a popular tourist draw located in southern Missouri on the border with Arkansas.
