"RAPID CITY, South Dakota, March 7, 2012 (ENS) - Several dozen Native Americans critical of TransCanada's proposed Keystone XL tar sands pipeline Monday blockaded two large trucks in a six-hour standoff at Wanblee, South Dakota."

"About 70 people joined the blockade, bringing food and water, and parking their vehicles across the road to prevent the trucks from traveling across the Pine Ridge Reservation in the south-central part of the state.

Eventually, five people were arrested by tribal police and the trucks went on their way to Canada under police escort. "
