April 27 (UPI) -- The death toll has hit 20 in a politically motivated attack on a highway in Colombia, as law enforcement has identified and is searching for a suspect.

Colombian Minister of Defense Pedro Sanchez said a man named Ivan Jacob Idrobo Arredondo, who goes by the name "Marlon," ordered the Saturday morning bomb attack on the Pan-American Highway, The BBC and The Miami Herald reported.

Arredondo is believed to be a former member of the Revolutionary Armed Forces of Colombia, generally referred to as FARC, who is part of a dissident group that broke off the group after it inked peace deal with the Colombian government in 2016.

"Those who carried out the attack ... are terrorists, fascists and drug traffickers," Colombian President Gustavo Petro said after the bombing.
