A veterinary receptionist from Worthing has been named among three Britons killed in a helicopter crash at the Grand Canyon.
Passengers Becky Dobson, 27, Jason Hill, 32, and Stuart Hill, 30, suffered fatal injuries in the crash, according to a news release from the Hualapai Nation Police Department.
The four survivors - British tourists Ellie Milward, Jonathan Udall, and Jennifer Barham, and pilot Scott Booth - were rescued at 2 a.m. local time on Sunday and airlifted to a hospital in Las Vegas.
A Foreign Office spokeswoman said: "We are providing support to the families of six British visitors involved in a helicopter accident at the Grand Canyon on February 10, and we are in close contact with the U.S. emergency services".
Hualapai Nation Police Chief Francis Bradley says navigating the rugged terrain in the dark made it hard for first-responders to reach the helicopter's wreckage.
Allen Kenitzer with the FAA Office of Communications confirmed in an email that the helicopter, a Eurocopter EC130, "crashed under unknown circumstances in the Grand Canyon".
During a Sunday afternoon press conference, Chief Bradley confirmed that all six passengers were from the United Kingdom.
Photos of the crash scene showed flames and dark smoke rising from rocky terrain.
