Bloodshed as tensions rise in Libya

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 unrest against Col Muammar Gaddafi's rule has been the second city, Benghazi, where 35 deaths were reported by one hospital alone.

As amateur video of demonstrators taking to the streets emerges, there are reports that the government has sent in elite military forces and militias to quell the unrest.
