American 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 Tuesday involved dozens protesting the Keystone XL pipeline. It would go through six states to refineries in Texas.

Before she was arrested, Hannah told The Associated Press the protesters want to be free from dependence on fossil fuels. The group calls for clean energy investments instead. Hannah says they hope President Barack Obama will not bow to oil lobbyists.

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

She has been arrested in the past for environmental causes.
