The Revolutionary Armed Forces of Colombia (FARC) rebel group has been weakened but not defeated yet, a top military official said, Xinhua reported.
The FARC was still capable of deploying explosives and mines, Edgar Cely, top commander of the Colombian armed forces, was quoted by the El Espectador newspaper as saying on Sunday.
"We have captured 22,200 explosive devices, deactivated 191 mine fields, and 6 car bombs," he said of military operations against the FARC.
Cely also said the leader of the rebel group, Guillermo Leon Saenz, alias "Alfonso Cano," no longer had the same authority as his predecessors.
In 2010, at least 450 government soldiers died and some 2,000 have been injured in operations against the FARC, which is considered a "terrorist" group by the Colombian government.
