The Security Council has approved the deployment of a U.N. political mission to monitor a cease-fire between the government of Colombia and the Revolutionary Armed Forces of Colombia, or FARC.

The resolution approved on Tuesday authorizes a mission made up of 450 observers and a number of civilians to be deployed in 40 widely dispersed locations to oversee the laying down of arms by the FARC and other aspects of the agreement.

On June 23, Colombian President Juan Manuel Santos and FARC rebels signed a cease-fire and rebel disarmament deal that moved the country to the brink of ending the 52-year war.
