BOGOTA, June 30 (Xinhua) -- Colombia's navy has seized more than 1.37 tons of explosives and 1,500 anti-personnel mines stockpiled by the country's armed rebels, the navy reported Monday on its website.

According to the navy, the cache belongs to the 32nd front of the Revolutionary Armed Forces of Colombia (FARC) and was discovered in the jungles of the country's southern Caqueta department.

"It could be the largest cache of explosives found this year," the navy said, adding it had destroyed the arsenal on site.

The FARC, often referred to by Colombian officials as a terrorist group, has been battling the state for 50 years.

"With information provided by a member of the terrorist organization, naval military intelligence followed up for two months, succeeding in locating the hidden cache in a jungle region," the navy said.

"According to authorities, (the leader of the front) is responsible for explosions of oil wells in southern Caqueta, leading to peasant and military victims," the navy added.

Colombian President Juan Manuel Santos has made peace talks with the FARC his priority after being reelected in mid-June, but no cease-fire agreement has been reached to date.
