(Adds criticism of Amr Moussa)
CAIRO, March 20 (Reuters) - More than 8,000 Libyans aligned with the rebel movement that rose up against Muammar Gaddafi have been killed in the revolt against his rule, a spokesman for the rebel movement told Al Jazeera on Sunday.
"Our dead and martyrs number more than 8,000 killed," Abdel Hafiz Ghoga said.
He criticised Arab League Secretary General Amr Moussa over comments that appeared to be critical of military action by the United States and its allies against Libya.
The Arab League had called for the imposition of a no-fly zone over Libya to protect civilians from Gaddafi's forces but Moussa on Sunday condemned "the bombardment of civilians".
"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," Egypt's state news agency quoted Moussa as saying.
Ghoga said: "Today, when the secretary general spoke, I was surprised."
"What is the mechanism that stops the extermination of the people in Libya, what is the mechanism, Mr. Secretary General? If the protection of civilians is not a humanitarian obligation, what is the mechanism that you propose to us?" he asked.
