"Challenges ahead are enormous" implementing Colombia peace dealListen /
"Enormous challenges" lie ahead for the Colombian people and their international partners in turning the historic deal with FARC rebels into a lasting peace.
That's the view of Jean Arnault who is tasked with leading the UN Mission there to monitor and verify the laying down of arms by rebel fighters.
He was speaking at the end of the World Summit of Nobel Peace Laureates which took place last week in the Colombian capital, Bogotá.
Colombian President Juan Manuel Santos was awarded last year's Nobel Peace Prize "for his resolute efforts to bring the country's more than 50-year-long civil war to an end."
Hélène Papper asked UN Special Representative Arnault what the value had been of bringing the prize winners together in Colombia, as the disarmament process gets fully underway.
