A commander of the Revolutionary Armed Forces of Colombia, also known as FARC, was killed in a bombing raid near the town of Riosucio on Monday.
Alfredo Alarcon Machado, better known as Ramón Ruiz, who led the 18th division of the FARC in northwest Colombia, was killed along with four other rebel members. The Colombian Air Force bombed a rebel position in the Choco province.
Ruiz is believed to be the main assistant of FARC representative Pastor Alape, who is negotiating with the Colombian government in peace talks in Havana, Cuba.
About 40 rebels have been killed since Colombia resumed bombing attacks after a ceasefire ended.
