Human heads dumped outside Mexican primary school
Five decomposing human heads have been left outside a primary school in the Mexican city of Acapulco.
In the latest chapter of Mexico's increasingly violent drug war, the heads were left on a footpath on Tuesday. They were in a white bag on top of a wooden box and clearly visible to pupils and pedestrians.
The previous day, police had discovered five decapitated bodies in another part of the city. Three were badly burned in a pick-up truck, while two were outside the vehicle.
Acapulco is a major tourist resort on Mexico's Pacific coast and was once a popular destination for Hollywood stars. However, its location on the Guerrero coast, which is used to smuggle drugs from South America, means it is now a battleground for the powerful drug cartels.
Just last month, three headless bodies were left in the main tourist area.
Last week, thousands of teachers and activists held a demonstration in the city after nearly a month of strikes over poor public safety in schools and appeals to authorities to improve security.
The Guerrero state governor has promised more police patrols and the installation of security cameras and panic buttons in schools.
At least 41,000 people have been killed since 2006, when the Mexican government launched a military crackdown on the drug gangs.
