Denver shooting: Gunman mistaken for 'a prank'

At least 12 cinema-goers have been shot dead by a gunman at a cinema in Colorado.

Around 50 other people were injured in the shooting which happened during a screening of the new Batman film 'The Dark Knight Rises' in Denver.

Evan Dozier, who was in the cinema at the time with his wife and three children, said some people first thought the attacker was a stunt.
