People lighting candles forming a cross on the ground in front of the house General Wojciech Jaruzelski in Warsaw on late December 12, 2011 to mark the 30th anniversary of the former communist regime's attempt to crush the Solidarity union by imposing martial law. On December 13, 1981, Jaruzelski imposed martial law and the security forces gunned down nine strikers at the "Wujek" coal mine in southern Poland. It was the bloodiest massacre under martial law.
