Takata airbags: Largest recall gets bigger

Japan's two biggest car makers, Toyota and Nissan, are recalling three million vehicles because of potentially faulty airbags that have been linked to eight deaths.

The president of Takata, the Japanese company which makes one in five of the airbags fitted to cars around the world, says it is still not clear why the airbags explode, firing pieces of metal at passengers.

Takata has already been forced to recall some 34 million vehicles for which it supplied components, at companies including BMW, Chrysler, Ford, Honda and Mazda.
