Two clowns in a traveling circus were shot to death in the middle of their performance by an unknown gunman, police in the eastern Colombian town of Cucuta said.

The gunman burst into the Circo del Sol de Cali and shot the clowns in front of an audience of 20 to 50 people attending a performance Monday night, police said. One of the clowns was killed instantly and the second died the next day in hospital.

Police said they knew of no motive for the killings.
