Six Colombian soldiers were wounded Thursday by an explosion attributed to the FARC guerrilla group in a rural area in the southern department of Huila.
The explosion was triggered when the military truck passed and is thought to have been a device planted by the Teofilo Forero group of the FARC, newspaper Milenio reports.
The soldiers were dressed in civilian clothes to perform administrative work.
The department of Huila has seen a recent increase in attacks attributed to the FARC.
