Update 4: Just hours after the shooting began, it looks like the final tallies are in.
Reuters reports that six people have been killed, including the two shooters: (those killed include one police officer, three people who were inside the JC Kosher Supermarket when the shooting began, and both of the suspected shooters).
Jersey City Mayor Steven Fulop told a news conference that there were multiple people deceased inside the store, where suspects reportedly had holed up and exchanged gunfire with law enforcement in a standoff that lasted for hours.
Several news media outlets including the New York Times, reported six people were dead, citing unnamed law enforcement sources, but Reuters could not immediately confirm the number of casualties.
The New York Times said the dead included a police officer, three victims who were in the store and two suspected gunmen.
Local media also reported the shooting unfolded at or near the JC Kosher Supermarket, though a city official told reporters there was no evidence the bloodshed was terror-related.
Two more officers and another bystander were wounded during the hours-long shootoff between police, federal agents and the shooters, who holed themselves up inside the supermarket for a period.
Though it started at a kosher supermarket, police and Jersey City's mayor said the attack wasn't a deliberate act of terror against Jews.

Another video shows officers marching up the street warning pedestrians to take cover.
Police said at least one gunman is "shooting at anyone they see on the street," according to NJ.com. The shooting reportedly started in a cemetery before the shooter fled into a nearby bodega, according to ABC New York. Another report claimed the two shooters targeted a Jewish grocery store and targets on the street outside, raising the possibility that this could be another anti-semitic attack. ABC said the shooting began at Bay View Cemetery, though there don't appear to be any kosher groceries close enough to the cemetery.
Police searching that cemetery have reportedly recovered a wounded officer's vehicle and radio. Surveillance footage has also been recovered showing one of the suspects entering a bodega after exiting from a van on the street.
No deaths have been reported yet, but at least one cop and one civilian have been shot. One of the gunmen has fired at a nearby school, prompting authorities to put all schools in the area on lock-down, and federal agencies, including the ATF, are on the scene near Martin Luther King Drive, where the shooting is taking place. That thoroughfare has been closed in both directions because of the shooting. Jersey transit has suspended rail and bus service on the west side of Jersey City.
