NICE, France (Reuters) - French authorities were trying to determine on Friday whether a Tunisian who killed at least 84 people by ploughing a truck into Bastille Day crowds had acted alone or with accomplices, but said the attack bore the hallmarks of Islamist militants.
Thursday night's attack in the Riviera city of Nice plunged France into new grief and fear just eight months after gunmen killed 130 people in Paris. Those attacks, and one in Brussels four months ago, shocked Western Europe, already anxious over security challenges from mass immigration, open borders and pockets of Islamist radicalism.
