(CNN) -- The No. 2 leader in a Marxist guerrilla group that has been at war with the Colombian government since the 1960s has been killed in a military raid, President Juan Manuel Santos said Thursday. Victor Julio Suarez Rojas, also known as Jorge Briceno Suarez and by his nom de guerre Mono Jojoy, was the military leader for the Revolutionary Armed Forces of Colombia, commonly called the FARC. Firefights between the military and the FARC continued into Thursday night, Defense Minister Rodrigo Rivera told CNN en Español. Rivera called the site where the military raid took place "the mother of all FARC camps." The camp was 300 meters (1,000 feet) long and had a bunker reinforced with concrete in the middle, he said. There were 13 satellite camps around the main camp, he said.
