Colombia's anti-government guerrillas have grown stronger under President Gustavo Petro’s three years in office. That strength was on display in brazen attacks this week that included a car bombing and the downing of a police helicopter — violence that left at least 19 people dead.
Authorities blamed both attacks on Thursday on renegade factions of the now-defunct Revolutionary Armed Forces of Colombia, the notorious FARC rebel group that for decades fought the government, carrying out assassinations, hijackings and bombings to undermine authorities in Bogota.
