Gaddafi vows 'long war' in Libya
Col Muammar Gaddafi says Libya will fight a "long war" after Western air strikes against his forces to protect rebel-held areas.
Military officials are said to be assessing the damage after at least 110 missiles were fired by the US and UK.
After an attack by French planes, some 14 bodies were lying near destroyed military vehicles outside the rebel-held city of Benghazi, Reuters says.
The head of the Arab League has criticised the bombardments.
His comments are significant because the Arab League's support for the no-fly zone was a key factor in getting UN Security Council backing for the resolution authorising the move.
"What is happening in Libya differs from the aim of imposing a no-fly zone, and what we want is the protection of civilians and not the bombardment of more civilians," said Arab League Secretary General Amr Moussa.
BBC state department correspondent Kim Ghattas says if no Arab states participate in the no-fly zone, and there is criticism from the Arab world, the US could decide to pull out. The UK and France had also been told the Arabs would participate, she adds.
Meanwhile, US military chief Adm Mike Mullen says aircraft from Qatar are moving into position near Libya to participate in the operation establishing a no-fly zone.
Earlier, he said the initial raids had been "successful".
US fighter planes and B-2 stealth bombers were also involved in the overnight raids early on Sunday, Pentagon officials said.
Cruise missiles hit at least 20 air-defence sites in the capital, Tripoli, and the western city of Misrata, they said.
Italy has now said its aircraft will be ready to take part in operations against Libya from Sunday.
Col Gaddafi's son Saif al-Islam called the attack a "big mistake".
"Believe me, one day you will wake up and you will find out that you were supporting the wrong people and you had made a big mistake in supporting those people," he told Christiane Amanpour for ABC This Week. "It's like the WMD [weapons of mass destruction] in Iraq. It's another story."
Libyan TV has broadcast footage it says showed some of the 150 people wounded in the attacks. It said 48 people had been killed.
There was no independent confirmation of the deaths and UK Finance Minister George Osborne told the BBC that such claims should be treated with caution as the military was striving to avoid civilian casualties.
Adm Mullen also said he had not received any reports of civilian deaths or injuries.
BBC defence correspondent Jonathan Marcus says coalition military planners will be urgently studying satellite and other reconnaissance imagery to determine how much damage has been done to Col Gaddafi's air defences and to see if some targets may have to be hit again.
He says they will also be monitoring the activities of Libyan government ground forces near key populated areas like Benghazi and Misrata, with any offensive action on their part bringing down urgent air strikes.
A rebel spokesman in Misrata told the BBC that pro-Gaddafi forces had launched fresh attacks on Sunday with heavy shelling in the city.BBC News
