Unanimously adopting resolution 1843 (2008), the Council, acting under Chapter VII of the United Nations Charter and following the recommendations by the Secretary-General in his letter of 12 November (document S/2008/703), authorized the immediate deployment of those additional capacities until 31 December. It expressed its intention to extend that authorization on the occasion of MONUC’s mandate renewal, underlining that the duration of stay of the additional forces would depend on the security situation in the Kivus.
