The Obama administration has announced plans to stand with Libyan demonstrators in their efforts to overthrow long-time dictator Moammar Gadhafi.
"We want him to leave and we want him to end his regime and call off the mercenaries and those troops that remain loyal to him," U.S. Secretary of State Hillary Clinton said at Monday's session of the U.N. Human Rights Council.
"How he manages that is obviously up to him and to his family," she added.
Clinton joined Russian Foreign Minister Sergey Lavrov and Ashton in Geneva on Monday to coordinate international action against Gadhafi's regime.
The European Union slapped an arms embargo, visa ban and other sanctions on Monday in an effort to halt the Libyan government's bloody crackdown.
The EU sanctions served as reinforcement to a U.N. Security Council vote held Saturday that issued an arms embargo against the North African nation. The world body stopped short of declaring a no-fly zone.
However, Sens. John Mccain, R-Ariz., and Joe Lieberman, I-Conn., said they favor a no-fly zone to prevent aerial attacks on the rebels. The lawmakers were in Jerusalem, one stop on their Middle East tour.
"We've always been for sanctions in cases like this but sanctions take too long," Lieberman said. "People are dying on the ground and that's why we need to act, I think, beginning with the no fly zone."
"I don't think the United States will quote go to war, but I do think the United States should declare the no-fly zones, make sure they're enforced, recognize a provisional government or governments and provide the assistance people need to keep from being massacred," said McCain, agreeing with his Senate colleague.
Meanwhile, anti-government demonstrators have gained control of several regions of the country as they move closer to the capital city of Tripoli.
Gadhafi has refused to step down despite massive rallies and international condemnation. Nevertheless, his foes have begun forming an interim government in the eastern part of Libya, and the revolt continues to spread in the west.
So far, an estimated 1,000 Libyans have been killed in the protests. More than 100,000 citizens have fled the North African country.
