东非共同体、根据罗安达进程设立的特设核查机制和大湖区问题国际会议的扩大核查机制联合小组的任务，是确定“3·23”恐怖组织是否已切实撤出基布姆巴。联合小组还确定，该组织仍占领着该地区，并继续通过征税和其他强制性征税来勒索民众。该组织还阻止联合小组成员继续执行任务，并迫使他们折返。
The joint EAC-Ad Hoc Verification Mechanism team set up under the Luanda process and the Expanded Joint Verification Mechanism of the International Conference on the Great Lakes Region (ICGLR), mandated to determine whether or not M23 had effectively withdrawn from Kibumba, has also established that the group is still occupying that locality and continues to hold the population to ransom through taxes and other mandatory levies. Moreover, it has prevented the joint team from pursuing its mission and has forced it to reverse course.
