BOGOTA, Nov 17 (Reuters) - The Colombian government and left-wing guerrilla group the National Liberation Army (ELN) are set to restart peace talks to end nearly 60 years of war next week, the government said.President Gustavo Petro, a former member of the M-19 insurgency who took office in August, has promised to bring "total peace" to the Andean country via negotiations with rebels and crime gangs.Colombian media reported he also confirmed talks, whose restart was announced last month, will begin on Monday, while a government source told Reuters it will be next week.Initial talks between the ELN and the government of Juan Manuel Santos began in Ecuador, later moving to Cuba, but were called off in 2019 by Santos' successor Ivan Duque because the ELN refused to halt hostilities and killed 22 police cadets in a bombing.Petro has also promised to fully implement a 2016 peace deal with the now-demobilized Revolutionary Armed Forces of Colombia (FARC) rebels, as well as to seek de-arming of crime gangs in exchange for reduced sentences and drug trafficking information."
