Colombian President Juan Manuel Santos and Marxist rebel leader Timochenko used 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 – shook hands on Monday on Colombian soil for the first time.
Some 2,500 foreign and local dignitaries attended the ceremony in the walled, colonial city of Cartagena.
