Watch the live feed from North Dakota.

Police are spraying #NoDAPL protesters with tear gas, using the LRAD stinger grenades, and firing rubber bullets into the crowd on the Highway 1806 bridge in North Dakota.

Police have formed a line with armored vehicles, concrete barriers, and razor wire. It is below freezing at about 27 degrees, and police have begun hosing down the unarmed crowd with a water cannon. Water protectors are using a semi truck in an attempt to remove burnt military vehicles, which the police chained to concrete barriers weeks ago to keep the bridge blocked on that highway.
