A US military team has arrived in the Liberian capital Monrovia to assess how best to bring stability to the war-ravaged West African country. The 20-strong group of military civil affairs specialists is being seen as a possible forerunner of a larger US peacekeeping force. Liberia's President Charles Taylor has agreed in principle to leave the war-torn country following demands from US President George W Bush for him to quit. But he said he would not accept an offer of asylum in Nigeria unless an American-led military force was in place.
