NEW YORK—A fatal gun rampage at a kosher grocery store in northern New Jersey this week is now being treated as an act of domestic terrorism and the FBI will oversee the investigation, federal and state law enforcement officials said on Thursday.
Six people, including the man and woman who carried out the attack, three civilians and a police officer died in a series of events that ended in a police shootout on Tuesday in Jersey City, New Jersey, located across the Hudson River from New York City.
