Interim Prime Minister Mahmoud Jibril called it a "historic moment" for the country.

I think it's for the Libyans to realize that this is the time to start a new Libya." Leaders across the globe hailed Gaddafi's death - as a moment of liberation. In London, British Prime Minister David Cameron noted the former dictator's victims - including those lost in the Lockerbie bombing.
