Colombian President Juan Manuel Santos and Marxist rebel leader Timochenko will use a pen made from a bullet on Monday to sign an agreement ending a half-century war that killed a quarter of a million people and made their nation a byword for violence.
After four years of negotiations in Havana, Santos, 65, and Timochenko, a nom de guerre for 57-year-old revolutionary Rodrigo Londono, will shake hands on Colombian soil for the first time.
Some 2,500 foreign and local dignitaries will attend the ceremony scheduled for 5 p.m. local time (1800 EST/2200 GMT) in the walled, colonial city of Cartagena.
