Climate activists say they have dumped 18 tons of coal in front of the Swedish government's headquarters in a protest against coal-fired power plants.
The Greenpeace activists say they want the government to stop Sweden's state-owned utility Vattenfall from investing in coal power. The company runs several coal-fired plants in Germany.
Greenpeace spokesman Anders Hellberg said Wednesday the group purchased the coal in Profen, Germany, and trucked it to Stockholm.
Police let the protesters picket outside the government office, while cleanup crews started removing the coal. It was not immediately clear whether the activists would face any charges.
