Moammar Gaddafi was the third of the region's leaders to be ousted by his own people in nine months, but the first to meet a bloody end.
The foreign ministry lauded the action, saying it should be a warning to others.
Muammar Gaddafi ruled Libya as the African country's dictator for more than four decades before he was overthrown and then killed in 2011. Born a Bedouin tribesman, Muammar Gaddafi attended military college and almost immediately set about plotting to overthrow Libya's ruler, King Idris I. He succeeded in 1969, taking power in a bloodless coup. Muammar Gaddafi was 27. He took the title of colonel, and in the 1970s he seemed to have philosophical pretentions, publishing his so-called Green Book of political philosophy and leading Libya in a path of "Islamic socialism" while ruthlessly suppressing dissent.

The news of Muammar Gaddafi's capture and death spread like wildfire across the world on Thursday. Media outlets, world leaders and locals in Libya were among those reacting to the news.
In response to Gaddafi's death, celebrations erupted in Libya and neighboring nations. Many took to the streets to chant, cheer and wave Libya's National Transitional Council flag.
Gaddafi's whereabouts had been unknown since Tripoli fell to revolutionary forces earlier this year. Most accounts agreed he had been holed up with heavily armed supporters in Sirte. The Mediterranean coastal town was the last major bastion of resistance since his 42-year reign ended in August.
