Nimule-Juba road ambush that claims five lives has saddened United Nations, says Under-Secretary-General for Peacekeeping Operations.
Jean-Pierre Lacroix expresses condolences to families that lost their love ones during the incident.
The deployment of Regional Protection Forces could minimize the risk of such incidents.
The Under-Secretary-General confirms that the deployment of the forces is ongoing and a number of other units will be sending their troops in the coming months.
UN is making possible effort to speed up that process of deployment, he adds.
