Libyan Army Defects And 'Liberates' Benghazi

Speaking from Benghazi, a local man named Benali, told Sky News that members of the Libya's armed forces have defected and that anti-regime protesters are now in control of the city.

Habib al-Obaidi, who heads the intensive care unit at the main Al-Jalae hospital, appeared to confirm the reports, saying the "Thunderbolt" squad arrived at the hospital with soldiers who had been injured in clashes with Gaddafi's men.

"They are now saying that they have overpowered the Praetorian Guard and that they have joined the people's revolt," said Mr al-Obaidi.

The doctor also confirmed the hospital had received the bodies of at least 50 people killed in clashes on Sunday afternoon.

Most had died of bullet wounds and another 100 others were admitted with serious injuries.

The news of further deaths comes as Libya's representative to the Arab League tendered his resignation in protest to "oppression against protesters".

There are also reports of clashes in central Tripoli between thousands of protesters and Gaddafi supporters.

At least 200 people have been killed in four days of anti-government protests, the most serious against Colonel Gaddafi since he came to power 41 years ago.

However, it has been a confusing picture in Libya as foreign journalists are banned from the country.

Furthermore, telecommunications have been interrupted and the internet cut off.
