A woman crossing a street was killed by an Uber self-driving sport utility vehicle in Arizona, police said on Monday, prompting the ride services company to suspend its autonomous vehicle program.

The accident in the Phoenix suburb of Tempe dealt a potential blow not only to Uber's strategy but the eventual roll-out of robot cars on public roads.

It was the first fatality from a self-driving vehicle, which are being tested around the globe in a high-profile race by global automakers and tech companies expecting that autonomous vehicles will transform transportation and the ride services business.
