Follow @NBCNewsWorld (http://twitter.com/NBCNewsWorld) By ReutersBOGOTA, Colombia -- Colombian forces have killed at least 20 Marxist FARC guerrillas in air and ground attacks near the border with Ecuador, an army general said Monday, the deadliest strike against rebels since the latest peace process started.
Despite talks to end 50 years of war, Colombia's government has vowed to keep up military operations even while the Revolutionary Armed Forces of Colombia, or FARC, called a two-month ceasefire as the two sides try to hash out a deal.
Colombian President Juan Manuel Santos is hoping a decade of U.S.-backed blows against the FARC has left the group sufficiently weakened to seek an end to the war.
In the most deadly attack since the two warring sides started negotiations in mid-October, an airstrike followed by a ground assault on three FARC camps in the southwestern Narino department killed at least 20 rebels late Sunday.
