Reydarfjördur, Iceland - Protesters locked themselves to machinery at the Kárahnjúkar dam site and blockaded the road leading to the area, stopping construction for a number of hours. 24 people were arrested, some of whom alleged they were physically or sexually abused by police and private security personnel. The dam is being built by the Pittsburgh based Alcoa Company to power an aluminum smelting plant despite being ruled illegal by the Icelandic high court. Activists want the dam project abandoned because of the massive amount of damage it will do to Iceland's environment.
