Rebel and government representatives in Ivory Coast have ended five days of talks in the capital Yamoussoukro without reaching an agreement on a date for disarmament.
Officials said talks on the issue would continue next Friday.
Rebel and government forces began withdrawing heavy weapons from the front line late last month, but the two sides have yet to work out the start date for comprehensive disarmament.
Such a move would fulfill a key condition of the latest Ivory Coast peace accord, which follows several failed peace deals in the West African country.
Rebels have controlled the northern half of Ivory Coast since an uprising in September 2002.
