On 1 March 2008 at 00:25 local time (05:25 UTC), Colombia launched a military operation, into Ecuador. According to Colombian authorities, the guerrillas responded militarily to this initial bombardment from a position in the vicinity of Santa Rosa de Yanamaru, on the Ecuadorian side of the border, killing a Colombian soldier, Carlos Hernández. A second bombardment was then carried out, resulting in the deaths of Raúl Reyes and at least 20 more FARC members. Two bodies, several documents and three laptops found in the guerrilla camp were returned to Colombia. This was the first time the Colombian military had killed a member of FARC's leadership council in combat. After this operation, Colombia increased its security measures nationwide, fearing FARC retaliation.
