UPDATE: One killed in Paris 'car bomb' - CNN

A judicial source said Paris's anti-terrorist unit had not been called in and for now ruled out the possibility of a terrorist attack.

"It is a criminal act, apparently a booby-trapped car," a police spokesman told Reuters, adding that police had not discounted the incident being a settling of scores.

LCI television reported the car's owner was previously known to the police.
