United Nations: The Security Council has extended the UN support mission in Libya for three more months and expanded its mandate to assist the North African country's transitional government in dealing with the threat of proliferation of arms, including surface-to-air missiles.

The UN Support Mission in Libya (UNSMIL) was established by the Council in September for an initial period of three months.

In the unanimously adopted resolution, the 15-member body extended the mandate until March 16 2012.

The Council said "the mandate of UNSMIL shall in addition include, in coordination and consultation with the transitional Government of Libya, assisting and supporting Libyan national efforts to address the threats of proliferation of all arms and related materiel of all types, in particular man- portable surface-to-air missiles".

The mission's initial mandate was to support the National Transitional Council (NTC) in its reconstruction efforts after he end of the conflict, including restoring the rule of law, drafting a new constitution, promoting reconciliation and preparing for elections.

The Council had in another resolution on October 31 called on interim authorities to take action to prevent the proliferation of arms, missiles and related materiel, saying they posed a security threat to the country and the region.

The NTC declared full liberation of Libya on October 23, eight months after the popular uprising began against the tyrannical regime of long-time ruler Muammar Gaddafi, who was eventually captured and killed.

Libya has since formed an interim government headed by Prime Minister Abdurrahim El-Keib.
