(CNN) -- At least one person was killed when an overpass bridge under construction collapsed in Belo Horizonte, Brazil, one of the host cities for the ongoing World Cup, firefighters said Thursday on Twitter. Two buses were also damaged in the collapse, said CNN affiliate TV Record, which cited firefighters. Images that circulated on social media showed a bus trapped by the collapsed concrete structure. Another photo showed at least one car was crushed. No further details were immediately available. The overpass traverses a major thoroughfare and is almost four miles from the 58,170-seat Estadio Mineirao where the World Cup games are being played in Belo Horizonte.
