The children of northeastern Colombia have a message for guerrillas blamed for the country's worst violence in over a decade -- as well as for rival militants tempted to take revenge.

The clashes between rival guerrilla groups have left 80 dead as Colombia braces for cutbacks in U.S. foreign aid under President Trump.

The unusually deadly violence delivers a devastating blow to the “total peace” program of the country’s first leftist president, Gustavo Petro.

Colombia on Wednesday reinstated arrest warrants for dozens of guerrilla commanders blamed for armed attacks that displaced 32,000 people and sparked the country's most serious security crisis in years.
