The concrete floor of one of thirty homes burnt down in the village of La Balsita, in the north of Colombia, during a massacre of peasants by right-wing paramilitaries. Paramilitaries of the self-named Farmers' Self-defences of Cordoba and Uraba (known by their Spanish acronym ACCU) entered the area in July of 1997 and in November they began the killings in earnest. According to human rights groups, to date paramilitaries have murdered some three hundred people in the area. The group's tactics were designed to strike fear into and terrorise the population. Very often the bodies that were found had been burnt with acid and had their eyes gouged out before they were killed.
