Although Colonel Gaddafi is reported to be in control of most of the Libyan capital Tripoli, anti-government protesters appear to be still very much in evidence in some suburbs of the city.
The latest amateur video, thought to have been filmed on Friday, shows what appear to be anti-Gaddafi demonstrators coming under heavy fire.
People are using mobile phones or small digital cameras, making it difficult to verify exactly what is happening. Some of the video footage obtained is from social networking sites on the internet.
Tripoli is home to two million of Libya’s six and a half million population, making control of the city central to control of the country itself.
The UN estimates more than 1,000 people have died in the uprising so far but Colonel Gaddafi’s son, Saif al-Islam, says the number of deaths has been exaggerated, although he also confirms that the Libyan air force has bombed four ammunition depots.
