More than 80 people are now reported to have been killed in Libya after a deadly crackdown, according to New York based human rights watchdog, Human Rights Watch.
Despite the risk to life, however, thousands of anti-Gaddafi demonstrators continue to defy authorities.
In Benghazi, further protests and fresh clashes have been reported between protesters and security forces. At least 35 people are now thought to have died in the eastern Libyan city.
Britain has described the crackdown as horrifying, following reports that heavy weapons and sniper units were being deployed against demonstrators. There are also claims the regime has drafted in African mercenaries, many wearing yellow helmets, to crush the uprising.
