Protesters clash with riot policemen during a demonstration in Barcelona on March 29, 2012 on a national strike day. Spaniards staged a general strike and took to the streets in anger at labour reforms, spending cuts and soaring unemployment, prompting scuffles with police. Police charged and arrested hooded rioters and bins were set on fire in Barcelona while there were some face-offs in Madrid, although most demonstrations passed off peacefully. AFP PHOTO / JOSEP LAGO
