TRIPOLI (Reuters) - Muammar Gaddafi's better armed and organized troops reversed the rapid westward advance of rebels on Tuesday as world powers meeting in London piled pressure on the Libyan leader to step down.
A conference of 40 governments and international bodies agreed to press on with a NATO-led aerial bombardment of Libyan forces until Gaddafi complied with a U.N. resolution to end violence against civilians.
It also set up a contact group comprising 20 countries and organizations, including Arab states, the African Union and the Arab League, to coordinate international support for an orderly transition to democracy in Libya.
"All of us must continue to increase the pressure on and deepen the isolation of the Gaddafi regime through other means as well," Secretary of State Hillary Clinton said after the London talks finished.
"This includes a unified front of political and diplomatic pressure that makes clear to Gaddafi that he must go."
