Up to 34 people were killed by Colombian guerrillas in what is described as the worst massacre since the country's President, Alvaro Uribe, took office nearly two years ago.
Survivors said the killers - thought to be members of the radical Marxist group, FARC - pulled the victims from their homes, bound their hands and feet and then shot them execution-style.
The killings occurred in a village close to the Venezuelan border, almost 300 miles northeast of Bogota early on Tuesday.
The guerrillas had accused the peasants of picking coca leaf for right-wing paramilitaries.
