Catalan separatist flags are waved as a crowd forms a human chain to mark the "Diada de Catalunya" (Catalunya's National Day) in central Barcelona September 11, 2013. Hundreds of thousands of Catalans held hands in a 400-km (250-mile) human chain across their region on Wednesday to press the Spanish government to let them vote on breaking away and forming their own country. A deep recession and cuts in public spending in Catalonia, a wealthy industrial region in northeastern Spain that accounts for a fifth of the country's economic output, have stirred discontent with the central government in Madrid.
