Violent clashes between local fans leave Cup host reeling

Brazil pledged to stamp out stadium violence on Monday after hooliganism marred a weekend first division league game, raising fresh doubts about its ability to stage a trouble-free World Cup.

President Dilma Rousseff said Brazil could not and would not tolerate soccer violence after fans of Atletico Paranaense and Vasco da Gama fought pitched battles in the southern city of Joinville.
