“The group unexpectedly announced on Wednesday that it would begin a truce for an unlimited time from Saturday. The move has been welcomed by the UN and the European Union.

The rebels attacked a patrol in a rural area of western Colombia. President Juan Manuel Santos described Farc’s ceasefire declaration as a ‘gift… full of thorns’. “
