Bogota, May 30 (RHC)-- Colombian troops killed 11 dissidents of the disbanded FARC guerrilla group, officials said Monday, as a fight looms over the future of a 2016 peace agreement in runoff presidential elections.  The military operation reportedly took place over the weekend in the south of the country as Colombians voted in the first round of presidential elections that left a hardline conservative and a former leftist guerrilla vying for the presidency. 

Defense Minister Luis Carlos Villegas said the operation in Montanita in the southern department of Caqueta left "11 dead and two wounded, including a minor who had been recruited by force."  The 13 were part of an armed faction commanded by a former FARC rebel leader, Rodrigo Cadete, who rejected the 2016 peace agreement with the government of President Juan Manuel Santos. 

The minister said the groups had been making threats against the mayor of the Caqueta capital of Florencia as well as an energy company in the region.  On the same day, the FARC denounced the killing of one of its demobilized member, John Jairo Pillimué Ruiz, who belonged to the demobilized zone Carlos Patiño, in the small town of Buenos Aires, in the north of the Cauca province. 

Under the peace accord, the Revolutionary Armed Forces of Colombia (FARC) disarmed its 7,000 fighters in order to join the political process as a political party. 

However, remnants of the rebel force -- estimated by the army to number about 1,200 -- are still active in the southern border areas, financing their operations through drug trafficking and extortion rackets.  Santos's government has yet to conclude a peace accord with the smaller National Liberation Army, or ELN. Negotiations with the ELN resumed in Havana earlier this month, and its rebel forces observed a five-day ceasefire during the elections. 

But the future of the peace accord has emerged as a key and divisive issue in the elections, which go to a runoff on June 17th.  The top vote-getter in Sunday's round of balloting was conservative Ivan Duque, who has vowed to rewrite the accord with the FARC if elected. 

Duque, who argues that FARC leaders got off too lightly, called for a "Colombia where peace coincides with justice" after the results were announced, reiterating his desire to revise — without "shredding" — the pact with FARC. 

He faces off against Gustavo Petro, a former Bogota mayor who received 25 percent of the vote to Duque's 39.7.  A past member of the now disbanded M-19 guerrilla group, Petro is the first leftist to contest a runoff in Colombia. 

Promising "change" and to fight corruption and inequality, Petro gained momentum as the campaign progressed, outdistancing two other candidates -- former Medellin mayor Sergio Fajardo and Santos's peace negotiator, Humberto de la Calle.
