United Nations monitors "today stored away the entirety of the FARC's registered individual arms", except for some that were exempted for transitional security at demobilisation camps, the United Nations said in a statement.
The ceremony is to be attended by Colombian President Juan Manuel Santos, who received last year's Nobel Peace prize for his efforts to reach a peace deal, along with FARC leader Rodrigo Londono, aka Timochenko, and United Nations representatives. A smaller number of weapons will remain in the hands of guerrillas until August 1, providing protection at 26 rural camps where the FARC's 7,000 fighters are making their transition to civilian life.
Army soldiers arrive to guard the Mariana Paez demobilization zone, one of many rural camps where FARC rebel fighters are making their transition to civilian life, one day ahead of an event with President Juan Manuel Santos in Buenavista, Colombia, Monday, June 26, 2017. In addition, it also claims that 77 out of 900 clandestine arms caches operated by FARC rebels have been found and emptied.
However, critics such as conservative political leader Alvaro Uribe said that the peace accord was too lenient on FARC members.
President Santos is now trying to strike a similar deal with the National Liberation Army (ELN), Colombia's second-largest left-wing rebel group.More news: 5 killed in cable auto accident in Indian-controlled Kashmir

The lay down is in compliance with the timeline agreed to between the Government and FARC-EP on 29 May, part of the historic deal that ended the half-century long conflict. That was blamed on a fringe extremist group, the Revolutionary People's Movement (MRP). The rifles will be melted down and turned into three monuments in Colombia, New York and Cuba, which hosted peace talks.
Some of them will get amnesty or reduced sentences for crimes committed during the conflict.
Drugs: The FARC have promised to help stamp out the drug production that has fueled the conflict in areas under its control.
On that date, the FARC is expected to deliver a list to the government of properties belonging to it to allow victims of the conflict to benefit from the sale and redistribution of the lands.
The accord eventually failed, paving the way for a decadelong bloodletting in which as many as 3,000 members of a FARC-aligned political party were gunned down.
