The hemisphere's longest war saw escalating skirmishes this weekend. Ten FARC rebels were killed in a fresh airstrike on Saturday, and more than 350 civilians were displaced after last Thursday's airstrike in the Cauca.
The rebel announcement raises the possibility of more bloodshed between the Colombian military and the rebel army it's been fighting for fifty years. Peace talks, however, were not halted.
The Tuesday night attack in Cauca state left 11 servicemen dead, renewing fears among optimistic Colombians that an end to five decades of internal war is farther than hoped.
