Colombian Rebels' New Strategy: Release Hostages

BOGOTÁ, COLOMBIA - Colombian leftist guerrillas freed four hostages on Sunday in the first of three hand-overs planned for this week. The release is a unilateral goodwill gesture that marks an attempt by the rebels to regain public credibility after a devastating year, say analysts.

The Revolutionary Armed Forces of Colombia (FARC) freed three policemen and a soldier who had been kidnapped in 2007 and were among the newest of what the FARC had considered its bargaining chips to force concessions from the country's conservative government.
