The fighting took place in the southwest on the border of Cauca and Valle del Cauca departments and killed a sergeant and four soldiers, the commander of Task Force Apollo, Jorge Humberton Jerez, told the Caracol radio station.
At the police station in the town of Puerto Rico, in Caqueta, the rebels failed to kill any officers when they fired explosives into the building but the blast killed a baby and its mother and father nearby, an official said.
One of the explosive charges struck the family`s house, causing the casualties, said Caqueta police chief Carlos Vargas.
The FARC (Revolutionary Armed Forces of Colombia), Latin America`s largest remaining guerrilla group, is believed to have about 9,000 fighters in mountainous and jungle areas of the country, according to government estimates.
FARC leader Timoleon Jimenez earlier this month denied that proposed negotiations with the government imply the guerrillas intend to surrender any time soon.
The FARC leader said the rich-poor divide in Colombia needed to be one of the issues on the table for future talks. (*)
