Twenty-six people were hospitalized and more than 200 people were injured after North Dakota law enforcement officers used water cannons, teargas, and other “less-than-lethal” weapons on people protesting against the Dakota Access pipeline on 20 November 2016.

The Standing Rock Medic & Healer Council said that injuries included multiple bone fractures from projectiles fired by police, a man with internal bleeding from a rubber bullet injury, a man who suffered a grand mal seizure, and a woman who was struck in the face with a rubber bullet and whose vision was compromised. The majority of the patients suffered hypothermia, a result of being soaked by water cannons, according to the group. Another young woman lost part of her arm when police launched an explosive device at her.

The incident began when water protectors attempted to move two burned trucks off a bridge just north of the protesters’ encampments. Law enforcement officers then began attacking the demonstrators with less-than-lethal weapons, including teargas, rubber bullets, and concussion grenades.

16 people were also arrested.
