Two people have been reported killed and 19 injured after an overpass collapsed in Belo Horizonte, the city that is due to host the World Cup's first semi-final on Tuesday.

The overpass, which was under-construction, collapsed onto another road trapping vehicles including a bus, which was said to be empty apart from the female driver - who was one of those who died.

The incident happened about 2.5miles from the Estadio Mineirao which is hosting the semi-final.

Brazilian media quoted a Fire Department spokesman that one person has been confirmed to have died and 19 taken to hospital with injuries, with City government officials saying another casualty has also died.

City officials have launched an investigation into the causes of the collapse.

The incident was about three miles from the Minas Tennis Club where the British Olympic and Paralympic teams will have their training base ahead of the Rio 2016 Olympics.

Brazil president Dilma Rousseff expressed her shock at the collapse on Twitter.

She wrote: "It is with sadness that we learn of the collapse of the viaduct in Belo Horizonte.

"In this moment of pain, we lend our support to the families of the victims.

"The government will help Belo Horizonte and the authorities with whatever it needs."
