Two Russian engineers kidnapped a week ago by Leftist rebels in north-west Colombia were set free, according to a Russian embassy official in Bogota. Russians Vladimir Molodtsov, 55, and Vladimir Larin, 47, are in good health, according to the embassy's second chief official Anatoli Kapko. He confirmed that the men had been seized by rebels of Marxist group, the Revolutionary Armed Forces of Colombia (FARC), and not by Colombia's second major Guerrilla force, the National Liberation Army (ELN), as earlier specified by police. Lithuanian-born Molodtsov and Larin worked for the company SGM, a contractor to the Spanish firm Dragados De Espana, which is building a hydroelectric dam in the north-west Colombian department of Antioquia. Authorities said that the two men were kidnapped on a rural road between the villages of Porce and Gomez Plata, some 500 kilometers (310 miles) northwest of the capital. Three Italians, meanwhile, kidnapped last Friday, are still being held. Bureau Report
