One of Madonna's tour trucks has been involved in a road accident in Sweden.
Police say a truck carrying the sound system for the Queen of Pop's concert in southwestern Sweden overturned and blocked parts of a highway.
Police say it is not clear what caused the truck to suddenly flip onto its side while driving toward Goteborg, and slide across several lanes, blocking rush hour traffic.

It was not immediately clear if the incident will affect Madonna's concert in the city on Wednesday.
Police said one person was injured and three passenger cars were damaged in the accident.
Madonna, who is due to perform in London later this month, is currently on her MDNA world tour, which kicked off in Israel in June.
This is the 53-year-old singer's ninth world tour. After performing in Europe she will head to the Americas before finishing in Australia in early 2013.
