One person was killed and a dozen others wounded in bomb attacks on police stations in the southern Colombian province of Nariño, authorities said.
The first strike was in the town of Tuquerres, where a device left in a cart exploded outside the police station, leaving one dead and six injured, paramedics said.
The blast also caused serious damage to the station and 10 neighboring homes.
A bomb planted inside the police station in Sandona nearly destroyed the building, damaged homes and injured six people, Mayor Camilo Gomez told reporters.
Nariño, which borders Ecuador, is plagued by violence from leftist guerrillas, right-wing paramilitaries and heavily armed smuggling gangs. EFE
