A topographer working for the United Nations, four policemen and three workers were injured on Wednesday when alleged FARC guerrillas attacked a group of coca eradicators, authorities said.
The attack took place in the area of the Pacific coastal town of Tumaco in the south western department of Nariño.
According to national authorities, FARC guerrillas fired grenades at the group of workers who were eradicating coca and marijuana plants.
The topographer was taken to a Bogota hospital for treatment. One of the injured policemen was taken to a hospital in Cali. The other injured were treated locally.
According to the U.N., topographers are sent on eradication missions to map the locations where eradications take place.
