At least 18 killed following two attacks in Colombia

At least 18 people died and more than forty were injured on Thursday following a bomb explosion and helicopter attack in Colombia attributed to different dissident factions of the former FARC guerrilla group, authorities reported.

In Cali, the country's third most populated city, a cargo vehicle with explosives detonated near a Colombian Aerospace Force base, in an incident that left six people dead and 71 injuries, according to the mayor's office.

Hours earlier, a National Police Black Hawk UH-60 helicopter participating in a coca leaf crop eradication operation was shot down in the municipality of Amalfi, in the department of Antioquia, leaving 12 officers dead.

Colombian President Gustavo Petro blamed the attacks on dissident factions of the former Revolutionary Armed Forces of Colombia (FARC) guerrilla group that rejected a 2016 peace agreement to end a prolonged internal conflict that has left more than 450,000 dead.
