The Hague's top prosecutor launched an investigation into Libyan leader Moammar Gaddafi on May 16

The Hague\'s top prosecutor launched an investigation into Libyan leader Moammar Gaddafi on May 16 Libyan rebels from Benghazi to Misrata poured into the streets to spray the sky with celebratory gunfire on Monday after the International Criminal Court issued an arrest warrant against Muammar Gaddafi. Scenes of joy erupted in the eastern city of Benghazi, the de facto rebel capital, moments after the war court issued arrest warrants for the embattled leader and two of his allies for crimes against humanity.
The Libyan strongman, who on Monday was slapped with an International Criminal Court arrest warrant for crimes against humanity, has clung to power in Tripoli in defiance of NATO air strikes in support of rebels.
ICC judges in The Hague also issued warrants for Gaddafi\'s son Seif al-Islam, 39, and the head of Libyan intelligence, Abdullah al-Senussi, 62, for murder and persecution.
The British foreign minister, William Hague welcomed the court\'s actions, saying that Gaddafi must be held responsible for attacks against civilians.
“The warrants further demonstrate why Gaddafi has lost all legitimacy and why he should go immediately. His forces continue to attack Libyans without mercy and this must stop.”
Renowned for his flamboyant dress sense and rambling rhetoric, the embattled Libyan leader faces an unprecedented challenge to his four-decade rule after anti-regime protests erupted on February 15.
International rights groups estimate that the death toll of the Libyan conflict runs into the tens of thousands and the oil-rich North African state is now split between the largely Gaddafi-controlled west and the rebel east.
While witnesses reported bloodshed, massacres and overwhelmed morgues after the indiscriminate shooting of civilians, Gaddafi dismissed the youth-led uprising and played up the revolution which brought him to power.
As a young colonel, Gaddafi on September 1, 1969 led a coup overthrowing the Western-backed elderly King Idriss and quickly established himself as a belligerent and unpredictable leader.
Reputedly born in a Bedouin tent in the desert near Sirte on June 7, 1942, Gaddafi alienated the West soon after seizing power, accusing it of launching a \"new crusade\" against the Arabs.
His idol was Egyptian president and fervent Arab nationalist Gamal Abdel Nasser, and he also variously declared himself a fan of Stalin and Hitler.
For decades linked to a spate of international terror attacks, Gaddafi\'s Libya was accused of using its oil wealth to fund and arm rebel groups across Africa and beyond.
Libya became an international pariah in the aftermath of the 1988 Lockerbie plane bombing, but relations began to thaw when it agreed in 2003 to pay compensation to the families of the 270 people killed.
Gaddafi also renounced terrorism and declared in 2003 that he was giving up the pursuit of weapons of mass destruction, prompting the lifting of UN sanctions.
The declaration also shored up dramatically Libya\'s ties with the West and was crowned with a visit in September 2008 by then US secretary of state Condoleezza Rice.
In February 2009, Gaddafi was elected chairman of the African Union, after having grown disillusioned with Arab unity and months after African tribal dignitaries bestowed on him the title of \"king of kings.\"
He is known for receiving world leaders in a Bedouin tent rather than in palatial buildings, and dresses in colourful flowing robes, surrounded by an entourage of female bodyguards.
Gaddafi\'s Libya has often been the focus of international attention.
In 2007, Tripoli released Bulgarian medics who had spent eight years in jail for allegedly infecting hundreds of Libyan children with HIV-tainted blood.
In 2008, the festive homecoming of convicted Lockerbie bomber Abdelbaset Ali Mohmet al-Megrahi, who was released by Scottish authorities on compassionate grounds, triggered fury in the United States.
And an apology to Libya the same year by Swiss President Hans-Rudolf Merz over the 2007 arrest of one of Gaddafi\'s sons, Hannibal, drew harsh criticism across the Alpine nation.
But the Arab world\'s longest-serving leader still managed to rile the West and Arab leaders with belligerent and provocative outbursts.
In July 2009, he blasted the UN Security Council as a form of \"terrorism\" in a speech at a Non-Aligned Movement summit.
In March the same year, he hurled insults at now Saudi King Abdullah at an Arab summit, telling him: \"You are always lying and you\'re facing the grave and you were made by Britain and protected by the United States.\"
Gaddafi can be quick to praise himself. \"I am the leader of the Arab leaders, the king of kings of Africa and the imam of the Muslims,\" he has said.
Having proclaimed Libya a Jamahiriya or \"state of the masses\" run by local committees in March 1977, Gaddafi is officially known as \"guide of the revolution\" as he has always shunned formal titles such as president.
He donned a white glove at an Arab summit to avoid \"soiling his hand\" by shaking with Arab kings.
Gaddafi\'s revolutionary \"Green Book,\" also published in 1977, offers \"a third theory of the world\" between capitalism and socialism that he vaunts as the only real solution for humanity.
Before the uprising, he had reportedly been grooming son Seif al-Islam -- one of eight children plus an adopted daughter who was killed in a US bombing raid in 1986 -- as his successor.
