Burundi has been engaged in a civil war marked by ethnic violence, which includes fighting between the Tutsi-dominated army and armed Hutu rebel groups. The fighting has caused widespread civilian casualties since the killing of democratically elected president Melchior Ndadaye in October 1993.
Having determined that the situation in Burundi continued to constitute a threat to international peace and security in the region and acting under Chapter VII of the UN Charter, the Security Council, by its resolution 1545 of 21 May 2004, decided to establish the United Nations Operation in Burundi (ONUB) in order to support and help to implement the efforts undertaken by Burundians to restore lasting peace and bring about national reconciliation, as provided under the Arusha Agreement.
