At least 13 dead in Honduran prison fire.

At least 13 people died Thursday in a fire at a prison in northern Honduras, CNN reported.

Among the dead was a prisoner who was decapitated. Video shot at the scene showed thick clouds of smoke billowing from the building.

The incident comes on the heels of another prison fire in Honduras that killed more than 350 people last month.

The cause of the fire at the prison in San Pedro Sula was not immediately known. Police Chief Ricardo Ramirez said shots had been heard from inside.

A fire last month in the central Honduran town of Comayagua killed 358 inmates. Two previous deadly prison fires have occurred in San Pedro Sula. In 2009, 103 people were reported killed and in 2004, 107 died.
