The number of people killed in three days of protests in Libya has risen to 84, according to the New York-based group Human Rights Watch.
The main focus of the demonstrations against Col Muammar Gaddafi’s 42-year-old rule has been the second city, Benghazi, where one hospital reported 35 deaths on Friday.
Protests are said to be continuing. State media have warned of retaliation.
Websites have been blocked and electricity shut off in some areas.
Media restrictions make it difficult to verify reports independently but the BBC has confirmed that websites including Facebook and al-Jazeera Arabic were blocked.
