Libyan leader Muammar Gaddafi's son, Saif al-Islam, has warned that civil war could hit the country. His comments came in a lengthy TV address to the nation broadcast as anti-government protests spread to the capital Tripoli.
He offered significant political reforms, and admitted that the police and army had made "mistakes", but said the death toll was lower than reported.
Human Rights Watch says at least 233 people have died since last Thursday.
It urged governments to tell Libya to stop the unlawful killing of protesters amid accounts of authorities using live ammunition against them.
