An International Red Cross spokesman says a special delegation has arrived in Colombia to pick up six rebel-held hostages. Yves Heller says the 17-member group arrived Saturday from Brazil aboard two helicopters and landed in Florencia, a city about 240 miles (380 kilometers) south of Bogota. The delegation is being led by Sen. Piedad Cordoba and will journey to the spot where three policemen and a soldier are to be released Sunday by the Revolutionary Armed Forces of Colombia. The FARC also has promised to release former Gov. Alan Jara and former lawmaker Sigifredo Lopez later in the week. The guerrillas announced Dec. 21 a unilateral release of six hostages, their first in nearly a year.
