A woman has been killed by an Uber self-driving car in the US state of Arizona and the ride-share company has suspended the service as a result.
The accident in the Phoenix suburb of Tempe is the first fatality from a self-driving vehicle, which are being tested around the globe.
The vehicle was in autonomous mode with an operator behind the wheel at the time of the accident, which occurred overnight on Sunday local time, Tempe police said.
"The vehicle was traveling northbound ... when a female walking outside of the crosswalk crossed the road from west to east when she was struck by the Uber vehicle," police said in a statement.
The woman, identified as 49-year-old Elaine Herzberg later died from her injuries in hospital, police said.
In a tweet, Uber expressed its condolences and said the company was fully cooperating with authorities.
