In October 1997 Security Council resolution 1132 established an arms embargo on Sierra Leone, at that time under military rule.
In June 1998 Security Council resolution 1171 lifted this territorial embargo but established a new arms embargo that did not apply to the government of Sierra Leone (no longer under military rule) but applied instead to the forces controlled by military commanders that had played a leading role in government and to the Revolutionary United Front (RUF).
Resolution 1171 required from States that they would notify all exports from their territories of arms or related matériel to Sierra Leone to the Committee established by resolution 1132. It also required that the Government of Sierra Leone would mark, register and notify to the Committee all imports made by it of arms and related matériel.
In September 2010 Security Council resolution 1940 lifted the remaining UN sanctions related to Sierra Leone after requests from Sierra Leone and advice from the sanctions Committee to do so.
