Protests against the Dakota Access Pipeline in North Dakota turned violent on Saturday.
Demonstrators supporting the Standing Rock Sioux Tribe faced off with private security officers from Dallas-based Energy Transfer Partners.
Video from the scene showed security officers threatening protesters with dogs.
As All Things Considered reported, hundreds of Native Americans from tribes across the country have set up a camp near the construction site in North Dakota. The Army Corps of Engineer approved the oil pipeline in July allowing it to run under the Missouri river close to the Standing Rock Sioux Tribe’s reservation.
Protesters worry that the $3.8 billion pipeline, which is slated to run through four states, could disturb sacred sites and affect the reservation’s drinking water.
