Nine Colombian soldiers were killed in an attack by guerrillas of the National Liberation Army (ELN) near the country's border with Venezuela on Wednesday, throwing peace negotiations between the rebel group and the government into question.
The attack, one of the most serious in recent months, took place in a rural area of El Carmen municipality in Colombia's Norte de Santander province, an important region for growing coca and producing cocaine.
The government of Colombia's leftist President Gustavo Petro restarted peace talks with the ELN last year as part of a drive for total peace in the Andean country, where almost six decades of internal conflict have left at least 450,000 dead.
Petro has called a meeting with the government's peace delegation, as well as guarantor countries - which include Venezuela, Mexico and Chile, among others - he said in a message on Twitter.
"A peace process should be earnest and accountable to Colombian society," Petro said in the message.
The government and the ELN concluded a first round of peace talks in Venezuela's capital Caracas at the end of 2022. A second round of peace talks began in Mexico earlier this year.
The ELN did not immediately comment on the attack or Petro's decision to talk with Colombia's peace delegation and guarantor countries.
The ELN is Colombia's oldest remaining rebel group, founded by radical Catholic priests in 1964, and the talks are the cornerstone of efforts by leftist Petro - himself a former member of another insurgent group - to bring "total peace" to Colombia.
Negotiations with the ELN under previous administrations faltered on the group's diffuse chain of command and dissent within its ranks, though Pablo Beltran, the head of the ELN delegation, and top commander Antonio Garcia have said fighters are on board with these talks.
