Native American communities believe that a new branch of the oil pipeline from Canada could damage local water bodies and disrupt their way of life.
Environmental activists and representatives of indigenous peoples of America blocked the construction of a controversial oil pipeline between Canada and the United States for several hours.
According to the NGO, the police arrested more than 160 demonstrators.
Amid chants of “Stop Line 3” and the sound of tribal drums, several hundred demonstrators, including actress and activist Jane Fonda, occupied a construction site near Lake Itasca in Minnesota before being pushed back by police.
The Line 3 pipeline, built by the Canadian company Enbridge, delivers oil from bituminous sands in the Canadian province of Alberta to refineries in Wisconsin.
However, the new route, which will increase the amount of oil transported, has met with opposition from Native American communities, who have warned that oil spills could damage local rivers.
