The preamble of the resolution additionally urged all states in the region, particularly Liberia, to co-operate with the Special Court for Sierra Leone. It remained concerned at the humanitarian situation, violations of human rights and serious instability in Liberia and Côte d'Ivoire. Support offered by the Liberian government to rebels in the civil war in Côte d'Ivoire and to the Revolutionary United Front rebels in Sierra Leone was determined to constitute a threat to international peace and security in the region.
