Policemen stand guard outside the Kiss nightclub where a blaze on the eve killed more than 230 people, on January 28, 2013, in Santa Maria, southern Brazil. Brazilian police arrested four suspects --two of the Kiss club's owners, along with a pair of musicians who starred in the ill-fated pyrotechnic show, in the wake of the nightclub fire that forced sports officials to defend preparations for the World Cup and Olympics..
