A week of amateur bullfights, commonly known as 'Corralejas', left 48 people injured in Colombia, local media has reported.

Every January hundreds of amateur bullfighters risk their lives jumping into an arena to taunt bulls in Colombia's unruly bull festivals.

The six-day event takes place in the state of Sucre.

It is described by locals as an explosive and sometimes lethal mixture of alcohol, music, violence and machismo.

An average of 20 participants die each year in the Corralejas, which have been held annually for more than 150 years in towns across Colombia's northern plains.

The only certain survivors in the arena are the bulls themselves as it is forbidden to kill the animals, unlike traditional bullfights with skilled matadors.

Colombia's most important Corraleja takes place on 20 January.
