'Relentlessly Negative': Hillary Blasts 2016 Media Coverage for 'Opening Door to Charlatans'

An eyewitness described a "nightmare" scene Monday after a van drove into a crowd in Toronto, killing 10 people and injuring 15 others.

Police officers captured the suspect minutes after news broke of the horrific incident.

"He's just hitting people one by one, going down," the witness said. "It was a nightmare."

The man said the scene was "gruesome," and was visibly shaken by what he saw.

Canadian Prime Minister Justin Trudeau also commented on the incident, tweeting that officials were monitoring the situation closely.

"I can't believe this is happening," the witness told reporters.

He said that the driver hit "anybody in his way" while riding along a sidewalk.

The driver, Alek Minassian, 25, lives in the Toronto suburb of Richmond Hill. Authorities have not ruled out terror as a possible motive in the attack.

The first of the victims was identified as Anne-Marie D’Amico, a young woman who worked at Invesco, a U.S.-based firm whose Canadian headquarters is near the scene of the attack.
