Joint monitoring
It provides for a joint coordination committee comprising the government, rebels and UN representatives that would be responsible for monitoring and managing the rebel camps.
The weapons would be locked in 70 metal containers and monitored by UN personnel.
"This agreement is in accordance with the aspiration of the people and aimed towards restoring permanent peace in the country and conducting free and fair elections," said Situala.
Thousands of rebel fighters have already reached the seven areas where these camps are to be built, but there is no infrastructure in place yet, reports have said.
