He said that some Islamic groups were behind the protests and turmoil, attempting to establish an "Islamic Emirate."

Seif al-Islam said 84 protestors were killed in Benghazi, denying early reports of 250 deaths of protestors.

He said that protestors attacked the road-blocks in Benghazi because they were angry. The army and the police were not prepared to battle people. Dozens of protestors were arrested, including some campaigners.

Some protestors in Benghazi have reportedly seized tanks and heavy equipments and worsened the turmoil in the country. Al- Alabiya said a section of troops in the city joined the protestors.

"What's happening in Libya is very dangerous," he said. "How will Libya feed its people if the country falls apart?"

Seif al-Islam said the country is composed of tribes and clans, and oil is the only source that keep the Libyans united.

He also denied the use of mercenaries, saying the reports about this were not true.
