An estimated 6,000 people have died in Libya as a result of the violent crackdown by the Muammar Gaddafi regime in response to opposition protests which sparked almost two weeks ago, the Libyan Human Rights league said on Wednesday.Gaddafi, orchestrating a populist response to rebels threatening his rule, blamed al Qaida on Wednesday for creating turmoil and told applauding supporters there was a conspiracy to control Libya and its oil.Gaddafi, who said no more than 150 people were killed in the unrest caused by "terrorists", told an audience of loyalists in a speech shown live on state television that if Washington or other foreign powers entered Libya they would face a bloody war.
