Relief workers in the Central African Republic say at least 10 people have been killed in clashes between the forces of the interim president and gunmen loyal to ousted president Francois Bozize.
The unrest began late Tuesday after Seleka fighters launched a weapons search operation in a northern section of the capital, Bangui, to disarm Bozize supporters.
Michel Djotodia, sworn in as interim president Sunday, led a Seleka rebel coalition that overthrew Mr. Bozize earlier this year.
Seleka launched the disarmament operation because heavy weapons fire had been heard in the area on Saturday.
State media reports say Mr. Djotodia called an emergency meeting on Wednesday to discuss the violence with community leaders.
Meanwhile, the FOMAC regional peacekeeping force is working to secure Bangui. A FOMAC commander told VOA his troops are trying to secure neighborhoods so residents can return.
The United Nations has expressed growing concern about C.A.R.'s security following the coup.
Last week, a senior U.N. official warned C.A.R. could become a failed state if quick action is not taken.
Humanitarian chief Valerie Amos told the U.N. Security Council that more than 200,000 people had been displaced internally and nearly 60,000 had fled to neighboring countries since the start of the crisis.
Meanwhile, Cameroon has closed its border with C.A.R. after an altercation between Seleka fighters and Cameroonian forces led to the death of a Cameroonian police official.
