Unknown attackers used explosives to strike a National Police station in Guapi, a town in Cauca province in Colombia's Pacific coastal region, wounding six people, civil authorities reported.
"The attack was against the police station located in the center of town," Guapi Education Secretary Dimas Orjuela told Caracol Radio.
The injured include two policemen, two adult civilians and two children, all of whom were taken to hospitals in the city of Cali and Buenaventura, the country's main Pacific port.
Guapi Interior Secretary Edith Milena Cabezas told the Cali daily El Pais that the attack took place a few minutes before midnight on Monday in an area where residents had gathered to welcome the new year.
Although authorities are still investigating the attack, Cauca police commander Col. Ricardo Augusto Alarcon told reporters that initial indications are that the strike was staged by the Revolutionary Armed Forces of Colombia, or FARC.
The explosion of multiple homemade bombs caused damage to the windows and doors of the police station.
The FARC, which is involved in peace talks with the government, declared a unilateral cease fire from Nov. 20, 2012, through Jan. 20, 2013.
However, according to a study released last Thursday by the CERAC center for conflict analysis, the guerrillas have staged at least 13 attacks since the cease fire supposedly went into force, most of them in the southwestern part of the country. EFE
