Reuters reports that “hundreds of U.S. military veterans on Friday have been arriving at a protest camp in North Dakota where thousands of activists, braving frigid conditions, are demonstrating against a pipeline project near a Native American reservation.”

“Veterans Stand for Standing Rock will spend the day building a barracks at the Oceti Sakowin camp near Cannon Ball and coordinating with protesters who have spent months rallying against plans to route the Dakota Access Pipeline beneath a lake near the Standing Rock Sioux reservation, organizers said.”

“Some of the more than 2,100 veterans who signed up on the group’s Facebook page have arrived at the camp, with hundreds more expected over the weekend. The veterans intend to form a human wall in front of police to protect protesters, who say the $3.8 billion pipeline poses a threat to water resources and sacred Native American sites.”
