Yosemite visitors 'presumed dead' in waterfall accident
Three visitors to a famed US national park are presumed dead after being swept over a 317ft (96m) waterfall.
Witnesses at Yosemite National Park in California said the trio had ignored warning signs and climbed over a metal barrier to pose for photographs.
The bodies of Hormiz David, 22, Ramina Badal, 21, and Ninos Yacoub, 27, have not been recovered.
Other visitors at Vernal Fall had shouted at them to get out of the raging water, a park official said.
The three had been on a day trip to the park, 200 miles (320km) east of San Francisco, on Tuesday.
After crossing a metal rail, the group were seen entering the water about 25ft above the fall.
"Several people urged the group members to step back from the river, since it was flowing swiftly and extremely cold," park spokesman Scott Gediman told the BBC by email.
Park rangers were continuing the search on Wednesday, primarily by combing the riverbanks.
