(CNN) -- The United Nations Security Council unanimously approved a resolution Thursday to deploy about 3,100 peacekeepers to a restive region in the Democratic Republic of Congo, the U.N. announced.
The intervention brigade will carry out targeted offensive operations and attempt to neutralize armed groups, the U.N. said in a statement.
The force will be based in the North Kivu province in the eastern part of the country. Government forces are battling a rebel group there called M23.
Fighting between the M23 and the army has displaced close to a million people in the province and more than 300,000 in the southeastern province of Katanga, the United Nations has said.
