Acting under Chapter VII of the United Nations Charter, the Council called upon the Sudanese government to fulfil its commitments made in the communiqué, including lifting restrictions on the delivery of humanitarian assistance, to co-operate with an independent investigation into human rights violations, and to resume dialogue with dissident groups in Darfur, particularly the Justice and Equality Movement (JEM) and Sudan Liberation Movement/Army (SLM/A).[5] Meanwhile, it endorsed the deployment of observers by the African Union to the Darfur region. Parties to the N’Djamena Ceasefire Agreement in April 2004 were urged to work towards an agreement and rebels were urged to respect the ceasefire and engage in peace talks.
