Tripoli : Scores of pro-democracy protesters in demonstrations have been killed by security forces, which were demanding the ousting of Muammar Gaddafi, the country's long time ruler.
Human Rights Watch said on Saturday that 84 people had died over the past three days.
A doctor in Benghazi told that he had seen 70 bodies at the city's hospital on Friday in one of the harshest crackdowns against peaceful protesters thus far.
"I have seen it on my own eyes: At least 70 bodies at the hospital," said Wuwufaq al-Zuwail, a physician.
Al-Zuwail said that security forces had also prevented ambulances reaching the site of the protests.
The Libyan government has also blocked Al Jazeera TV signal in the country and people have also reported that the network's website is inaccessible from there.
Protesters shot
Marchers mourning dead protesters in Benghazi, Libya's second-largest city, reportedly come under fire from security forces, as protests in the oil-exporting North African nation entered their fifth day on Friday.

Mohamed el-Berqawy, an engineer in Benghazi, told that the city was the scene of a "massacre," and that four demonstrators had been killed.
"Where is the United Nations ... where is (US president Barack) Obama, where is the rest of the world, people are dying on the streets," he said. "We are ready to die for our country."
Verifying news from Libya has been difficult since protests began, thanks to restrictions on journalists entering the country, as well as internet and mobile phone black outs imposed by the government.
Tens of thousands of anti-government protesters seeking to oust Gaddafi took to the streets across Libya on Thursday in what organisers called a "day of rage" modelled after similar protests in Tunisia and Egypt that ousted longtime leaders there. Gaddafi has ruled Libya since 1969.
Pro-government supporters also were out on the streets on Friday, according to the Libyan state television, which broadcasted images labelled "live" that showed men chanting slogans in support of Gaddafi.
The pro-Gaddafi crowd was seen singing as it surrounded his limousine as it crept along a road in the capital, Tripoli, packed with people carrying his portrait.
Deadly clashes
Deadly clashes broke out in several towns on Thursday after the opposition called for protests in a rare show of defiance inspired by uprisings in other Arab states and the toppling of Egypt's Hosni Mubarak and Tunisia's Zine El Abidine Ben Ali.
The worst clashes appeared to have taken place in the eastern Cyrenaica region, centred on Benghazi, where support for Gaddafi has historically been weaker than in other parts of the country.
Libya's Quryna newspaper reported on Thursday that the regional security chief had been removed from his post over the deaths of protesters in Bayda.
Libyan opposition groups in exile claimed that Bayda citizens had joined with local police forces to take over Bayda and fight against government-backed militias, whose ranks are allegedly filled by recruits from other African nations.
Political analysts say Libyan oil wealth may give the government the capacity to smooth over social problems and
reduce the risk of an Egypt-style revolt.
Gaddafi's opponents say they want political freedoms, respect for human rights and an end to corruption.
The government has proposed the doubling of government employees' salaries and released 110 suspected anti-government figures who oppose him - tactics similar to those adopted by other Arab governments facing recent mass protests.
