Gunmen have killed two journalists as they walked in a park in southern Guatemala.

Prensa Libre newspaper director Miguel Angel Mendez Zetina says the daily's correspondent Danilo Lopez, and Federico Salazar, of Radio Nuevo Mundo, were killed Tuesday in the southern town of Mazatenango.

Mendez Zetina says Lopez had recently filed a complaint against Jose Linares Rojas, the mayor of San Lorenzo, for threatening him over stories he wrote about a lack of transparency in Linares' government administration.

Local firefighters said a third person was wounded in the attack.
