WASHINGTON — Actress Daryl Hannah has been arrested in front of the White House along with other environmental protesters who oppose a planned oil pipeline from Canada to the U.S. Gulf Coast.

The sit-in on Tuesday involved dozens protesting the Keystone XL pipeline. It would go through Montana, South Dakota, Nebraska, Kansas, Oklahoma and Texas to refineries in Houston and Port Arthur, Texas.

Before she was arrested, Hannah told WRC-TV the protesters want to be free from the "death and destruction" that fossil fuels cause. The group is calling for clean energy instead.

Hannah sat down on the sidewalk near the White House and refused orders from U.S. Park Police to move.

She has been arrested for environmental causes in the past.
