Western countries, the European Union and United Nations have imposed sanctions on Libya and frozen government assets. Here are details of the sanctions:
Australia: Australia has imposed sanctions on Gaddafi and his inner circle, including bans on financial dealings with 22 individuals and on entering Australian territory.
Austria: Austria has ordered a freeze of any assets belonging to Gaddafi, his family and other associates. Its central bank has said some 1.2 billion euros ($1.66 billion) in Libyan assets were deposited in Austrian institutions.
Britain: Britain has frozen 12 billion pounds ($19.2 billion) of Libyan assets, Prime Minister David Cameron said on March 11, and has also said it has lifted his diplomatic immunity.
-- The asset freeze covers not only assets held in the names of Gaddafi and his children, but assets controlled by them.
-- The Gaddafi family is reported to have billions of dollars of investments in London, while Gaddafi's son, Saif al-Islam, owns a 10 million pound ($16 million) home there.
-- Britain also extended a freeze on Gaddafi family assets to a further 20 members of his entourage and impounded around 100 million pounds of Libyan currency.
Canada: Canada said on March 1 it had frozen C$2.3 billion ($2.4 billion) worth of assets belonging to Gaddafi.
-- Ottawa announced a clampdown on doing business with Libyan institutions on Feb. 27 and later said it had blocked unspecified financial dealings the Libyan government had planned to carry out in Canada.
Germany: The German Economy ministry said on March 10 it had frozen bank accounts belonging to Libya. Access to money of the Libyan Central Bank, Libya Africa Investment Portfolio, Libyan Foreign Bank and Libyan Investment Authority is forbidden in Germany until further notice, the ministry said.
Italy: The Bank of Italy on March 2 ordered financial institutions to report any suspicious movements in accounts held by members of the Gaddafi family or his government.
Luxembourg: Luxembourg froze accounts of the Libyan Central Bank and the Libyan Investment Authority on March 8. The accounts held less than 1 billion euros ($1.39 billion).
Japan: Japan imposed sanctions on Libya on March 8, including freezing assets of Gaddafi and several other Libyans, in line with the UN Security Council resolution. They also include a ban on Gaddafi and others from travelling to Japan.
Russia: President Dmitry Medvedev banned Gaddafi and his family from Russia and from carrying out financial transactions in the country, the Kremlin said on Monday.
-- Russia said on March 10 it would ban weapons sales to Libya, effectively suspending billions of dollars worth of arms contracts with Gaddafi's government. The ban includes financial loans and training aimed at bolstering Libya's military.
-- Unrest in Libya cost Russia $4 billion in weapon sales to the region, a senior Russian arms official said last week.
Spain: Spain has frozen a tourism project on the Costa del Sol owned by Gaddafi and is seeking other assets and bank accounts linked to the Libyan leader, the foreign ministry said.
-- Spain revoked two defence material export licences to Libya, Prime Minister Jose Luis Rodriguez Zapatero said on March 9. The two licences were suspended by Spain to Libya in February, but Zapatero said they would be now revoked.
Switzerland: Switzerland raised up pressure on Gaddafi on March 4 by banning transfers of money that could end up in the hands of his family and associates. The decision could affect Libyan oil company Tamoil, which operates a 72,000 bpd refinery in western Switzerland.
-- Switzerland said on Feb. 24 it was freezing any assets Gaddafi and his family might have in the country. The Swiss foreign ministry said it was not clear if Gaddafi and parties close to him actually did have assets in Switzerland.
-- Libya's foreign ministry denied Gaddafi holds banks accounts in Switzerland or in any other bank around the world.
United States: The United States named on Wednesday 14 companies owned by Libya's state oil firm as subject to sanctions, including prominent east Libyan operator Agoco, aiming to cut off a key source of funds for Gaddafi's regime.
-- The US Treasury said on March 11 that it had extended asset-freeze sanctions to Gaddafi's wife, four of his children and four senior officials in his government. The action bans US persons from conducting transactions with them and seeks to freeze assets they may have under US jurisdiction.
-- President Barack Obama signed an executive order on Feb 25 freezing the assets of Gaddafi, his family and top officials, as well as the Libyan government, the country's central bank and sovereign wealth funds.
European Union: EU governments agreed on Wednesday to impose sanctions on Libya's National Oil Company, in line with the March 17 UN resolution, and to add four other oil firms to EU measures, diplomats said.
-- The EU expanded sanctions against Libya on March 21, adding 11 individuals and 9 entities to its banned list, although the targets were not specified. Gaddafi and 25 close associates were already on the list, as was the Libyan Investment Authority.
-- EU governments had originally approved a package of sanctions on Feb. 28 against Gaddafi and his closest advisers, including an arms embargo and bans on travel to the bloc.
-- EU states have also added the $70 billion Libyan Investment Authority, the Libyan central bank, and three other institutions to a sanctions list.
ICC: The International Criminal Court prosecutor said on March 2 he would open an investigation into the violence in Libya after the UN Security Council referred the case to the Hague-based court.
United Nations: The Security Council imposed an arms embargo, travel bans and asset freezes on Gaddafi and his family on Feb 26, and referred Libya's crackdown on anti-government demonstrators to the International Criminal Court.
-- On March 1, the UN General Assembly unanimously suspended Libya's membership in the UN Human Rights Council because of violence against protesters by Gaddafi forces.
-- The resolution was adopted by consensus in the 192-nation General Assembly on the basis of a recommendation from the 47-member Geneva-based council, the principal UN rights forum. That body accused Libyan authorities of "gross and systematic violations of human rights".
-- On March 17 the Security Council voted to authorize a no-fly zone over Libya and "all necessary measures" -- code for military action -- to shield civilians against Gaddafi's forces.
