The FBI treats the attack earlier this week at a Jewish supermarket in Jersey City, US, as a case of domestic terrorism.
The Public Prosecution Service in the state of New Jersey has announced this.
Two people opened fire on the Jewish store on Tuesday. A firefight with the police followed. A policeman, three civilians and the two perpetrators were killed.
One of the two perpetrators appeared to have left online anti-Semitic statements, just like hate reports against the police, The New York Times reported earlier.
