River disaster kills at least 18
Rescue workers locate the body of a victim
At least 18 people have been killed in a canyoning accident in central Switzerland.
Earlier reports that another body had been found in the water turned out to be false.
A local police spokesman said the victims came from Australia, New Zealand, the UK, Canada, the United States, South Africa and Switzerland.
The police said it would take "days or weeks" until all the victims were identified.
Most of the fatalities suffered injuries to the head and the canyonists were all wearing identical protective gear - so dental records will have to be used for identification.
Canyoning is an adventure sport which involves climbing down gorges, and body surfing down mountain rapids and waterfalls without a raft.
The victims had apparently been swept down from a nearby canyon, possibly in flash floods following a sudden thunderstorm.
"I saw huge pieces of wood in the water," said Andreas Haesler. "Then I saw bodies - one on its stomach, one on its back. They were all wearing life jackets but it was clear they were dead."
Helicopters and teams of rescuers are on site and an investigating judge has been called to the scene.
New Zealander John Hall, who is in hospital with back injuries, told his mother Ann that a lot of his friends had been killed, but that staff were shielding him from the extent of the tragedy.
Thunder and lightning
The expedition had been organised by Adventure World, a Swiss company based in nearby Wilderswil, which is popular with Americans and Japanese.
"It's awful," said Georg Hoedle, one of the company's managers, as he choked back tears at a news conference.
"We've been organising canyoning for six years and until now have only had the occasional broken leg."
The stream flows into a river which in turn empties into Lake Brienz around 60 kilometres (37 miles) southeast of the Swiss capital, Bern.
Examining Magistrate Martin Trapp, who is investigating the accident, told the BBC there had been thunder and lightning in the afternoon and he would be looking at whether the storm could have caused the deaths.
The authorities have set up a special phone line for worried relatives on (41-31) 634-20-51.
Canyoning is considered dangerous even in the best weather conditions.
The tragedy comes just months after a British teenager was killed canyoning in the Blue Mountains near Sydney, Australia.
Siobhan Halls, 17, who had not been wearing a safety helmet, died when her body was dragged under water. Her body was found wedged beneath rocks.
