NEW YORK — A man in a rented pickup truck mowed down pedestrians and cyclists along a busy bike path near the World Trade Center memorial Tuesday, killing at least eight and injuring 11 others in what the mayor called "a particularly cowardly act of terror."The driver was shot in the abdomen by police and taken into custody after jumping out of the truck with what turned out to be a fake gun in each hand and shouting "Allahu Akbar!" officials said. His condition was not immediately released.Two law enforcement officials who were not authorized to discuss the investigation and spoke of condition of anonymity identified the attacker as 29-year-old Sayfullo Saipov. He has a Florida driver's license but may have been staying in New Jersey.
