NEW YORK — A man in a rented pickup truck drove onto a busy bicycle path near the World Trade Center memorial Tuesday, killing at least eight people and injuring several others in what the mayor called "a particularly cowardly act of terror."

The 29-year-old driver was shot by police after jumping out of the truck with what turned out to be a fake gun in each hand, officials said. He was taken into custody. His condition was not immediately disclosed.

Police said the vehicle, a rented Home Depot truck, entered the bike path on West Street a few blocks from the new World Trade Center and mowed down several people. The truck also slammed into a small yellow school bus, injuring two adults and two children.

ABC News confirmed the shooter as Sayfullo Saipov, of Tampa, Florida. An eyewitness said Saipov "sprinted toward the group of kids" after crashing onto bike path and hitting school bus.

Sources told ABC News that Saipov screamed "Allahu Akbar," during the incident, a key reason authorities are looking at terrorism as possible motive.

A paintball gun and a pellet gun were found at the scene, police said.

Witnesses described a scene of panic and blood, with people screaming in fear and the path strewn with bodies and mangled bicycles.

The attack closed roads across the western edge of Manhattan along the Hudson River and sent uniformed officers rushing to the neighborhood as people prepared for Halloween festivities, including an annual parade through Greenwich Village.
