The Force Commander of the United Nations Mission in Sudan Lt. Gen. Jasbir Singh Lidder said the biggest challenges facing the Comprehensive Peace Agreement (CPA) are the issues of border demarcation and Abyei.

Lt. Gen. Lidder told Miraya FM that the only violation of the CPA was that took place in Malakal in December 2006.

Lidder will leave his post within days after heading the forces of the UN Mission in Sudan during the past two years.
