The shooting that shocked Jersey City yesterday hit the tight-knit Jewish community and left six people dead after two armed men barricaded themselves in a kosher supermarket, Hungary’s Jewish news portal reports.

Gunfire started in the local cemetery where police had identified two men who were behaving suspiciously. The two young gunmen shot and killed one of the officers and injured the other. They then fled the scene and barricaded themselves in a kosher supermarket where they shot customers and exchanged fire with the police. According to the Jerusalem Post, the gunmen found their way into the supermarket randomly. On Tuesday evening, Jersey City police chief said there is no indication that the incident was terrorism-related”, the V4 news agency reported.

The hours-long shootout at the supermarket claimed five lives, including the two gunmen, on top of the officer killed in the cemetery. Although police are yet to release any information on the identity of the victims, the Israeli media was quick to publish their names. According to Collive, the victims of the deadly shootout included Moshe Hersh Deutsch, the 24-year-old son of the leader of the Satmar (Hasidic) community and Leah Mindel Ferentz, the store owner’s wife.

Jersey City mayor Steven Fulop paid tribute to murdered police officer, Joseph Seals. He tweeted that 40-year old was a “great cop and an excellent father of five children”. The ordeal has rattled New Jersey’s small Orthodox Jewish community of around one hundred families, most of whom have moved to the neighborhood from Brooklyn in recent years.
