NEW YORK -- New York City's mayor says a truck attack in lower Manhattan killed eight people and was a "cowardly" act of terror.
Mayor Bill de Blasio says the attack on a bike path near the World Trade Center "was an act of terror, and a particularly cowardly act of terror aimed at innocent civilians."

New York Gov. Andrew Cuomo called it a "lone wolf" attack. He says there's no evidence to suggest it was part of a wider plot.
Witnesses described a chaotic scene of a white pickup truck hitting bicyclists on a path near the World Trade Center and then slamming into a school bus. They say the driver got out of his vehicle brandishing what appeared to be a gun in each hand.
An anonymous law enforcement official told the Associated Press that witnesses told police that the 29-year-old suspect shouted "allahu akbar" after exiting the vehicle.
The New York Police Department posted on its Twitter feed that one person was in custody after being shot by officers.
A U.S. official familiar with the investigation into what happened says the man is from Uzbekistan and came to the U.S. in 2010. Another official says the man has a Florida license but may have been staying in New Jersey.
A witness said the truck had also collided with a small bus and one other vehicle.
