BOGOTA, April 9 (Xinhua) -- At least three soldiers were killed and six others wounded in an ambush while patrolling near the municipality of Ituango in Antioquia department, the Colombian army said Saturday.

"On the night of Friday, April 8, a military vehicle ... was attacked by explosives embedded along the road apparently by terrorists from the organized armed group Structure 18," the Command of the Seventh Army Division said in a statement.

The six wounded soldiers are recovering in a regional health center.

The attack has been attributed to dissidents of the now disbanded guerrilla group the Revolutionary Armed Forces of Colombia (FARC), said the army.

The FARC guerrilla group was demobilized in 2016 and is currently an opposition political party. And yet some dissident members did not turn in their weapons and continued operations.

"(We) will file the corresponding complaints with the Attorney General's Office for the use of illicit means and methods of war, which violates international humanitarian law," the statement said.
