Children at a primary school in the Mexican city of Acapulco are being taught how to protect themselves in the event of a shooting.
It is not the usual kind of lesson on an average curriculum but the police initiative is thought necessary due to the massacres and shootouts happening daily in a city riddled with drug violence.
Far from frightening the children, the youngsters have responded positively to the graphic demonstrations.
Acapulco is a favourite tourist destination but locals and visitors alike have been warned to avoid night time activities due to the clashes between rival gangs.
In Mexico as a whole, around 30,000 people have been killed since President Felipe Calderón began a crackdown against the drug cartels four years ago.
