COPENHAGEN, April 24 (Xinhua) -- A passenger car collided with the audience stands at a monster truck event in the Bjerke district of Norway's capital city of Oslo on Sunday afternoon, injuring several people, including six who were taken to the hospital, the Oslo Police Operations Center confirmed via social media.

       "Six people have been taken to hospital for further check-ups. We are still working on site to obtain witness information," said the Oslo Police on Twitter.

       Norwegian media NRK quoted Thomas Broberg, a task chief of Police at the scene, as saying that the accident occurred at around 18:19 local time (1619 GMT) causing "chaos" and "some of the injuries are classified as serious."

       It was a passenger car that drove into the stands, not a monster truck, Oslo police operations chief Sven Christian Lie confirmed to Norwegian news agency NTB.
