Central African Republic violence draws condemnation, travel warning BANGUI, Central African Republic, Dec. 27 (UPI) -- U.N. Secretary-General Ban Ki-moon condemned attacks in the Central African Republic by Seleka rebels and the U.S. State Department issued a travel warning. "These developments gravely undermine the peace agreements in place and the efforts of the international community to consolidate peace in the Central African Republic," a representative for Ban said in a statement issued Wednesday from New York. Earlier this week, the Seleka rebel coalition seized a regional capital, Kaga-Bandoro, and was reportedly within 200 miles of Bangui, the national capital. The republic, a landlocked country bordered by Chad, Cameroon and the Democratic Republic of Congo, is among the poorest countries in the world. Ban appealed to all parties to refrain from acts of violence and "to ensure the protection of civilians and to respect human rights, in conformity with international instruments to which the Central African Republic is a party." The State Department issued a travel warning Monday, recommending against "all but essential travel outside the capital, Bangui." "U.S. citizens should review their personal security situation and consider taking advantage of commercial flights," the travel warning said. Embassy Bangui is able to provide only limited emergency consular services. An emergency message for U.S. citizens issued Tuesday said the embassy was "suspending normal operations until further notice." The State Department encouraged U.S. citizens to leave Central African Republic "until the security situation improves."
