Dissatisfied with the country’s worsening economic troubles and displeased with proposed austerity measures, thousands of demonstrators clashed with police in Madrid Tuesday. The protesters formed a human chain around the parliament building while police fired bullets at and beat the most violent in the crowd with truncheons. At least 22 people were arrested while 32 were injured, including four policeman. The protest was timed to the new 2013 budget, which will be announced by the government Thursday and includes cuts in inflation-linked pensions, taxes on stock transactions, the implantation of green taxes, and the elimination of several tax breaks. The region of Catalonia, which is responsible for 20 percent of the national output, called for an early election on Nov. 25 that could lead to a referendum on secession.
