According to BBC, Colombia's FARC rebel group has formally disarmed completely as an armed group, putting an end to half a century of violent conflict in the country.
However, the event which ended the disarmament process, President Juan Manuel Santos said the "peace was real and irreversible".
The president said, the former guerrillas will now work on forming a political party.
Meanwhile, the FARC leader, Mr Rodrigo Londoño, known as Timochenko said: "Farewell to war. Farewell to arms, welcome to peace!".
President Santos is now trying to strike a similar deal with the National Liberation Army (ELN), Colombia's second-largest left-wing rebel group.
The handover of 7,132 weapons was a key demand in the peace process signed last year, which marked the end of the Farc's 52-year conflict in which 260,000 people were killed.
