A man in a pickup truck killed seven people when he drove onto the West Side bike path in lower Manhattan Tuesday afternoon — and then shouted “Allahu Akbar” as he got out of the car with fake guns, police sources said.

The suspected terror attack happened around 3:15 p.m., when a man in a flatbed pickup truck from Home Depot veered onto the bike path at West St., a few blocks north of Chambers St., police said.

The suspect, who was shot by police, then plowed his car into up to 23 people on the path, killing seven and injuring more than a dozen others, according to cops.

He continued driving south and hit another car, then got out and displayed “imitation firearms,” police said.

The man then shouted, “Allahu Akbar,” according to police sources.

Witnesses described a scene of terror, as people fled for safety.
