Bogota - Six soldiers were killed and four were injured Monday in south-western Colombia in an attack that was allegedly perpetrated by leftist rebels, according to media reports in Bogota.

Reports did not give details as to whether the soldiers entered a minefield or were ambushed by the Revolutionary Armed Forces of Colombia (FARC).
