Al Jazeera television broadcaster, citing medical sources, reported that 61 people had been killed in clashes in Libya early on Monday.

Anti-regime protests in Libya have spread to the capital of Tripoli, where thousands of protesters gathered in capitals' Green Square amidst rumors that the country's dictator Muammar Gaddafi has fled Libya for another country.

Gaddafi has left his country for Venezuela or Brazil, a report said on Monday.

Government's crackdown on people to put down the protests against Gaddafi's 41-year rule turned out to be counterproductive as massive demonstrations continued on Sunday.

The repression became bloodier when security forces opened fire on thousands of people gathered to mourn for those killed on Saturday clashes in Benghazi.

Meanwhile, Libyan envoy to the Arab League Abdel Moneim al-Honi and the country's Ambassador to China Hussein Sadeq Al Misurati, have resigned to join the protests.

Al-Honi has submitted his resignation "in protest against the acts of repression and violence against demonstrators."

Al Misurati told Al Jazeera TV that he was not "honored to represent a regime that kills its people."

An opposition leader has said that all tribes across the country have joined the anti-government protests, reports said.

Latest figures show the death toll from clashes in Libya's massive popular uprising is nearing 300.
