At least eight people were killed and several were injured Tuesday after a rental truck tore through a bike path in Lower Manhattan in New York City.
The suspect, who reportedly shouted “Allahu akbar” ("God is great") after exiting the vehicle, was hospitalized after being shot by the New York Police Department and was expected to survive.
The attack was being investigated as terrorism by the FBI and NYPD, Fox News confirmed.
