The international reactions to the Libyan Civil War were the responses to the series of protests and military confrontations occurring in Libya against the government of Libya and its de facto head of state Muammar Gaddafi.
Many states and supranational bodies condemned Gaddafi's regime over its attacks on civilian targets within the country. Virtually all Western countries cut off diplomatic relations with Gaddafi's government over an aerial bombing campaign in February and March, and a number of other countries led by Peru and Botswana did likewise. The regime's use of the Libyan Air Force to strike civilians led to the adoption of United Nations Security Council Resolution 1973 to create a Libyan no-fly zone on 17 March, though several countries involved in the resolution's enforcement have also carried out regular strike missions to degrade the offensive capacity of the Libyan Army and destroy the regime's command and control capabilities, effectively acting in de facto support of anti-Gaddafi forces on the ground. Many members of the international community, including the United Nations, the Arab League, and the African Union, explicitly recognized the anti-Gaddafi National Transitional Council as Libya's legitimate representative, with many of those countries explicitly describing it as the legal interim government of the country due to the perceived loss of legitimacy on the part of Gaddafi's regime.
Many states also either issued travel advisories or attempted evacuations. Some evacuations were successful in either going to Malta or via land borders to Egypt or Tunisia; other attempts were hindered by tarmac damage at Benghazi's airport or refusals of permission to land in Tripoli. There were also several solidarity protests in other countries that were mostly composed of Libyan expatriates. Financial markets around the world had adverse reactions to the instability with oil prices rising to a two-and-a-half-year high.
