An Uber self-driving car hit and killed a woman crossing the street in Arizona, police said on Monday, the first fatality caused by an autonomous vehicle and a potential blow to the technology expected to transform transportation.

The taxi company said it was suspending North American tests of its self-driving vehicles, which are currently going on in Arizona, Pittsburgh and Toronto.
