Indonesian police say seven Japanese tourists have gone missing while scuba diving off the resort island of Bali.

Chief of Nusa Penida police Maj. Nyoman Suarsika said the group, including two master divers, left Friday morning on a boat they hired. They were diving around mangroves in Crystal Bay when strong winds and heavy rains hit the area and have not been seen since Friday afternoon.

A list provided by police shows the group includes one man and six women.

The search for the missing divers started Saturday morning involving police, the National Search and Rescue Agency and fishermen, guided by the two Indonesian skippers from the divers' boat.

Nusa Penida is about 20 kilometers (12 miles) east off Denpasar, Bali's capital.
