Fighters loyal to Libyan leader Moammar Gadhafi are reinforcing their grip on the capital, Tripoli, as a growing popular uprising spreads across the eastern half of the country and anti-government forces consolidate control over key cities. In Tripoli, Gadhafi's stronghold, protest organizers are calling for new rallies Thursday and Friday, raising the potential for a new bloody confrontation there. Residents in the Libyan capital say the streets were largely deserted Wednesday, with people afraid to leave their homes. Armed militiamen and pro-Gadhafi loyalists - a mix of Libyans and African mercenaries - are reportedly roaming through Tripoli and fortifying the city's outer defenses. Security agents are said to be searching for people considered disloyal to the regime. U.S. President Barack Obama called Wednesday for the regime to stop targeting citizens. "We strongly condemn the use of violence in Libya," Obama said. "The American people extend our deepest condolences to the families and loved ones of all who have been killed and injured. The suffering and bloodshed is outrageous, and it is unacceptable, so are threats and orders to shoot peaceful protesters." Anti-government forces claimed Wednesday to have taken control of Misurata, Libya's third-largest city about 200 kilometers from Tripoli, marking the westernmost advance of the opposition movement. People fleeing across the border into Tunisia reported heavy fighting in the town of Sabratha, 80 kilometers west of the capital. President Obama said the actions of Libyan demonstrators, and others in the region, represent their desire to live a better life. "As one Libyan said, 'We just want to be able to live like human beings'," noted Obama. "We just want to be able to live like human beings. It is the most basic of aspirations that is driving this change. Throughout this time of transition, the United States will continue to stand up for freedom, stand up for justice, and stand up for the dignity of all people." Protesters and mutinous army units continue to consolidate their hold on nearly the entire eastern half of Libya's 1,600 kilometer-long coastline, setting up rudimentary governments and manning checkpoints along the main roads. .
