The United States said Wednesday it was considering sanctions and other means to pressure Moammar Gadhafi's regime to halt attacks against Libyans as violent clashes spread throughout the country. President Barack Obama planned to speak publicly about the situation later Wednesday.
"Everything will be on the table," Secretary of State Hillary Rodham Clinton said. "We will look at all the possible options to put an end to the violence, to try to influence the government."
White House spokesman Jay Carney called the violence "abhorrent."
Carney said that "a lot of options are under review _ sanctions, other options" to end the fighting in the North African country, where protesters are demanding an end to Gadhafi's 42-year reign but facing a fierce and bloody crackdown.
Obama, who planned to speak from the White House at 5:15 p.m. EST, had stayed silent in public as violence overtook Libya and the U.S. focused on getting American citizens out of the country. Evacuations finally began Wednesday.
State Department spokesman P.J. Crowley said the U.S. would ask other countries to get some Americans outside of the capital to safety. He spoke as American and other non-Libyan passengers were boarding a ferry to leave Tripoli for the Mediterranean island of Malta.
Crowley said Libyan authorities were helping in the process and checking passports.
Militiamen loyal to Gadhafi clamped down Wednesday in Tripoli while the rebellion controlling other parts of the country claimed new gains. Hundreds have been killed as militiamen loyal to Gadhafi roam the streets firing at will.
The White House stopped short of directly criticizing the unpredictable Gadhafi and did not call for his ouster. As it did with Egypt, the U.S. is walking a fine line given the uncertainty ahead in Libya, though America's strong alliance with former Egyptian President Hosni Mubarak gave the U.S. a more pointed stake there.
Obama never directly called for Mubarak's ouster before an uprising forced his exit on Feb. 11. For now the White House appears to be adopting the same stance in Libya although the U.S. ties with Gadhafi are far more tenuous.
"This is not about individual leaders. It's not about personalities," Carney said when asked Wednesday if Obama believes Gadhafi should continue to lead Libya. He said what was important that people's voices are heard.
Possible sanctions include asset freezes and travel bans on Libyan officials.
Crowley wouldn't rule out efforts to establish a no-fly zone to prevent Libyan aerial attacks, but acknowledged that the international process involved would be challenging.
A no-fly zone "is a very difficult thing to actually perform," he said. "We want to see an end to the violence. And any action that we take along those lines would require international support. There is obviously a significant degree of difficulty in doing something like that."
The U.S. will be consulting with the United Nations on future steps, Crowley said, and Clinton met Wednesday with the foreign minister of Brazil, which holds the rotating presidency of the U.N. Security Council.
Unease over the safety of U.S. citizens intensified after attempts to get some out on Monday and Tuesday were unsuccessful. Late Tuesday, the State Department announced that American citizens would be evacuated by ferry.
The mercurial Gadhafi _ once termed the "mad dog of the Middle East" by President Ronald Reagan _ has long flummoxed U.S. officials. He is notoriously unpredictable and has been known to fly into rages at real or perceived slights.
The Obama administration did not outline any specific steps to coerce or punish the Libyan regime, with which the U.S. has built a wary partnership after years of branding Gadhafi a terrorist sponsor. After decades of hostility, the U.S. and Libya normalized ties during President George W. Bush's presidency after Gadhafi renounced terrorism and weapons of mass destruction. But relations have been far from fully cordial.
U.S. officials said Washington would join other nations to address Libyan behavior at the U.N. Security Council. They renewed calls for Gadhafi's government to talk with opponents, and cast the political unrest there as part of a regional uprising against political and economic stagnation that must be addressed by the Arab governments of the Middle East and North Africa.
Gadhafi delivered a defiant speech on national television Tuesday in which he vowed he will not step aside. He said he would die a martyr's death fighting those rebelling against him. The address was filled with references to his standing up to the United States and other world powers and threats to execute protesters.
In addition to the tone, the speech unnerved U.S. officials because it was delivered in front of the rubble of the Tripoli compound that the U.S. bombed in 1986, killing Gadhafi's young daughter. As he spoke state-run television repeatedly showed a courtyard statue of a clenched fist crushing a U.S. fighter jet.
With the potential for Gadhafi to foment anti-American or anti-Western sentiment and Libya teetering on the brink of what some fear will explode into a full-blown civil war, administration officials have so far repeatedly invoked their primary concern of ensuring the safety of U.S. citizens there.
"As always, the safety and well-being of Americans has to be our highest priority. We are in touch with many Libyan officials directly and indirectly and with other governments in the region to try to influence what is going on inside Libya," Clinton told reporters at the State Department.
Crowley said the department was trying to get 35 nonessential staff and family members of personnel at the U.S. Embassy in Libya out of the country. The State Department ordered them to leave Monday.
The department also believes there are several thousand dual U.S.-Libyan nationals and about 600 private U.S. citizens in Libya.
