Violence has flared anew in Central African Republic's capital with an attack on a U.N. peacekeeping convoy.

The U.N. peacekeeping spokeswoman Miriam Dessables said four were wounded in the attack Wednesday by elements of the Christian militia calling for the president to resign.

Barricades have gone up throughout the capital and gunmen have been firing in the air.

The country has been unstable since a Muslim rebel coalition overthrew the president last year and installed their own president, Michel Djotodia, who was later forced to resign.

President Catherine Samba-Panza has struggled to restore order in this impoverished nation where Christian and Muslim militias regularly attack civilians from rival communities.

A U.N. peacekeeping force took over in September and on Oct. 10, a peacekeeper was killed by gunmen.
