Colombia's government said Tuesday it was tightening security after details emerged of a FARC rebel plot to murder ex-president Alvaro Uribe. Defense Minister Juan Carlos Pinzon said he met with Uribe "to inform him of the detection of a plan by the FARC's Teofilo Forero Mobile Column to make an attempt on his life." Pinzon said President Juan Manuel Santos ordered authorities "to guarantee the security and integrity of the former head of state and protect him, as well as to get those responsible for these threats." The defense chief also said Uribe — a vehement critic of peace talks with the rebels, and likely presidential reelection hopeful next year — would get whatever security he and his family need — in addition to their normal 300-person detail.
