The smaller of Colombia's two main guerrilla insurgencies has freed a man held captive since Oct. 30, the International Committee of the Red Cross told Efe Wednesday.

Members of the National Liberation Army, or ELN, handed Jose Eulogio Vera over to the ICRC in a rural area outside Arauquita, a town near the Venezuelan border, at around 8:00 p.m. Tuesday.

Vera was reunited with his family in the nearby town of Saravena after a medical exam showed he was in good health.

The ELN had earlier claimed responsibility for the abduction of the 54-year-old Vera, who was working for a company contracted by the local unit of California-based Occidental Petroleum and Colombian state-controlled oil company Ecopetrol.

Thus far this year, the ICRC has participated in the release of 25 individuals (19 Colombians and six foreigners) being held by the Revolutionary Armed Forces of Colombia, or FARC, Colombia's largest guerrilla organization, and the ELN.

The ELN targets the mining and oil sectors to signal opposition to the involvement of multinational companies in exploiting the Andean nation's natural resources. EFE
