-- Local law enforcement and protesters pushing to block the Dakota Access Pipeline in North Dakota clashed today as tensions between the two groups continue to rise while the controversial pipeline nears completion.
Hundreds of protesters, who call themselves "water protectors," gathered today at the north side of the camp they have set up on federal land to confront dozens of police officers clad in riot gear regarding law enforcement's use of what protesters say is a culturally sacred site.
Police had set up a surveillance post to monitor protesters on a hill directly north of the camp. Native American groups say the hill being utilized by law enforcement groups contains sacred burial grounds, and the police use of this hill has been a point of ongoing tension between the "water protectors" and local authorities.
The tension over the issue led to a standoff today, when police destroyed a bridge that the "water protectors" had set to up cross a small river inlet that separates the camp from the hill where the police are stationed.
Tribal groups built a bridge last night to cross the river inlet that separates the camp from their culturally sacred sites, in order to give them access to the burial grounds, and overnight law enforcement destroyed the bridge, inciting anger among many of the protesters.
Protesters today swam across the river and lined up in the water, many locking arms and praying, as well as yelling at the police.
Eventually, the "water protectors" left the river and returned to the southern part of their camp. Tribal leaders urged the water protectors to back down.
"Protesters are trying to gain access onto private property also known as the Cannon Ball Ranch. Early this morning, law enforcement witnessed a group of protesters building a hand-made, wooden pedestrian bridge across the Cantapeta Creek. Officers responded and ordered protesters to remove themselves from the bridge and notified them that if they cross the bridge they would be arrested," Morton County Sheriff's Department public information officer Donnell Hushka said in a statement today regarding the incident.
"Protesters continued to gain access by swimming and using other boats to get across the river," Hushka added. "Protesters involved in this activity are violating numerous federal and state laws."
The Sheriff's Department arrested one individual following the standoff "who was aiding in illegal activity by purchasing canoes and kayaks to be used for crossing the waterway."
The Sheriff's Department also confirmed that authorities used "less-than-lethal ammunition" and deployed pepper spray and tear gas.
In a statement today, Cass County Sheriff Paul Laney said, “In my 27 years in law enforcement, I have never seen such an absolute disregard for the law, or other people’s rights because of someone else’s ideology. The idea that because you have a strong opinion about something means you can threaten, harass and intimidate other American citizens is just plain wrong. I took an oath to protect the First Amendment, but I also took an oath to protect citizens from this continual harassment and intimidation.”
