In Columbia, Farc rebels have handed over all of their personal weapons, completing the transfer of arms a day ahead of a revised schedule. United Nations monitors said that a total of 7,132 weapons have been registered and boxed away. <br/><br/>The arms handover is a key condition in last year's peace agreement. The deal seeks to end more than five decades of conflict and negotiations between Colombia's largest left-wing rebel group and the government.<br/> <br/>President Juan Manuel Santos, who won a Nobel Prize for his efforts in securing the peace deal with the Farc, will attend a symbolic ceremony today in the town of Mesetas, south of Bogota, to mark the end of the disarmament process. <br/><br/>Mesetas was once a Farc stronghold during the 52-year conflict with the state in which 260,000 people lost their lives.
