A truck that plowed into a group of people during Bastille Day celebrations in Nice on Thursday is just the latest onslaught on a region that was still healing from string of brutal terror attacks.
Exact motivations in the attack were still unclear French officials said "the individual who was driving the truck was neutralized," and a terrorism investigation has been opened.
And the incident in Nice comes a month after an ISIS supporter killed two French police officers in the Paris suburb of Magnanville in a stabbing overnight on June 14, and a series of other terror attacks around the continent:
