A fast-moving fire roared through a crowded, windowless nightclub in southern Brazil early Sunday, filling the air in seconds with flames and a thick, toxic smoke that killed more than 230 panicked partygoers, many of whom were caught in a stampede to escape.
Plans to celebrate the 500 days to go until the 2014 World Cup were halted by FIFA and local organizers in light of the tragic nightclub fire that killed more than 230 people in southern Brazil on Sunday.
FIFA canceled an event on Monday in Brasilia, the capital of the state where the tragedy occurred, as mourners began to hold funerals for the victims of the fire.
Despite the incident, FIFA has maintained it is confident in Brazil's security plans for the World Cup.
Organizers said they felt "extremely sad for what happened" and expressed "their sympathy to the families of the victims."
The unveiling of the official World Cup poster was scheduled for Monday but also was postponed. The poster will be unveiled Wednesday after a meeting of the local organizing committee in Rio de Janeiro.
FIFA Secretary General Jerome Valcke, who began a four-day visit to Brazil on Sunday, posted a message on his Twitter account expressing sympathy.
"Very sad to hear of the tragedy in southern Brazil. My condolences to the families of victims," wrote Valcke, who is scheduled to visit Fortaleza, Brasilia, Salvador and Rio de Janeiro in the center and north of the country.
Santa Maria, where the fire took place, is about 155 miles from Porto Alegre, one of the 12 World Cup host cities, in the same state of Rio Grande do Sul. The nightclub fire, which appeared to be the world's deadliest in more than a decade, is likely to again increase scrutiny of safety efforts ahead of the World Cup and the 2016 Rio de Janeiro Olympics. FIFA reiterated its belief that the local organizing committees and Brazilian city, state and federal agencies are up to the task.
"FIFA has full confidence in the security plans of the LOC and the local authorities," soccer's governing body said in a statement.
The 2016 Rio organizing committee expressed "solidarity with the families and friends of the victims of this tragedy," adding "it wishes a quick recovery to those affected."
The International Olympic Committee said that "we simply send our sympathies to friends and families."
Hosting the World Cup and Olympics two years apart has heightened attention on security and crime issues in Brazil, although the discussion has focused possible violence. South Africa's relatively high rates of violent crime were similarly scrutinized before the 2010 World Cup, but that tournament was held without major incident.
Because of the tragedy, the Rio Grande do Sul state soccer federation canceled Sunday matches in its first-division regional championship. There was a minute of silence honoring the victims before matches across the country.
