Colombia's FARC rebels began disarming Wednesday under a historic peace deal, beginning the delicate transition from guerrilla army to political party after more than half a century at war.

After weeks of mustering its troops at designated disarmament zones, the FARC, or Revolutionary Armed Forces of Colombia, was set to begin an inventory of its weapons and destroying munitions under United Nations supervision.

"I'm abandoning my rifle for a broom," said guerrilla Maritza Gonzalez at the FARC's hot, dusty camp in San Jose de Oriente, in northern Colombia.

Three armed guerrillas in combat fatigues guarded the entrance to the rudimentary camp, where a steady stream of trucks

delivered bags of cement and workers scrambled to finish building a kitchen, mess hall, bathrooms and a laundry area.

Gonzalez, 54, has been a guerrilla since the age of 14. She said she was hopefill for the future and planned to reunite with her five brothers and four sisters.

"Let's hope this leads to peace," she told AFP.

President Juan Manuel Santos, who won the Nobel Peace Prize in October for his efforts to end the country's 53-year conflict, called the disarmament "historic news forColombians" inatweet.

FARC leader Rodrigo "Timochenko" Londono tweeted that the leftist rebels were laying down their guns “with enthusiasm."

The disarmament of the country's largest guerrilla army will leave rival movement ELN -- currently engaged in rocky peace talks with the government - as the only rebel group still waging a multi-sided war that has killed 260,000 people.
