The driver of the truck that smashed into a crowd watching fireworks in the French Riviera city of Nice, killing at least 84, has been formally identified, police sources said Friday. He was named by Nice-Matin newspaper as 31-year-old Franco-Tunisian Mohamed Lahouaiej Bouhlel, whose identity papers were found in the vehicle after the attack on France's July 14 national holiday. Police said he lived in Nice. According to sources, he was already known to police for minor criminal offences. It is reported that Bouhlel was married with three children but that he was barred since 2012 from his family's house due to domestic violence charges. Bouhlel also worked as a delivery truck driver, according to the Nice-Matin news report. Police are awaiting DNA confirmation that it was Bouhlel's body at the driver's seat. Police shot the driver dead after he drove the truck two kilometres through a crowd along the palm-lined Promenade des Anglais. Interior ministry spokesman Pierre-Henry Brandet said 84 people were killed and scores injured, including 18 in "critical condition".
