The U.N. Security Council has extended its peacekeeping mission in Liberia for three more months.

The council voted unanimously on Wednesday to extend the mission while reaffirming its readiness to consider withdrawing pending a proposed review of the situation in mid-November.

In June, Liberia assumed responsibility for its security for the first time since civil war ended in the West African country 13 years ago, leaving behind a reduced U.N. force of about 1,200 troops in a supporting role.

The peacekeeping force was deployed in 2003 to help stabilize Liberia after a four-year civil war. That conflict and a previous civil war are said to have killed more than 250,000.
