The parties signed a comprehensive ceasefire on 3 May, and, the same day, the UN Security Council passed Resolution 1479, which established the UN Mission in Côte d'Ivoire (MINUCI, Mission des Nations unies en Côte d'Ivoire) to monitor implementation of the Linas-Marcoussis Accord. MINUCI was headed by, and would assist, Tévoédirè, the UN Secretary General's Special Representative. MINUCI arrived in Ivory Coast on 27 June 2003; initially comprising 34 officers, it was planned to expand to 76 personnel by the end of the year. Notwithstanding the ceasefire, "extreme violence" continued in the western part of the country, necessitating in late May a joint operation involving elements of both government and rebel forces, as well as French and ECOWAS peacekeepers.
