On 20 October 2011, Gaddafi was captured and killed near his hometown of Sirte. In a ceremony on 23 October 2011, officials of the interim National Transitional Council declared, `` We declare to the whole world that we have liberated our beloved country, with its cities, villages, hill - tops, mountains, deserts and skies.
