Libya Braces for 'Day of Anger'
Anti-government activists in Libya have been using social networking sites to rally support for protests on what they are describing as a "day of anger".
There were reports of clashes in two cities late on Wednesday, with about four people reported dead in the eastern city of al-Bayda.
Dozens of people were injured in violent demonstrations on Tuesday night in the eastern city of Benghazi.
The unrest there followed the detention of an outspoken government critic.
Pro-democracy protests have recently swept through several Arab nations, with the presidents of Tunisia and Egypt forced to resign amid growing unrest.
But this week's demonstrations were the first display of defiance in Libya, where dissent is rarely tolerated.
It is not clear what kind of response there has been to the call for more protests on Thursday.
The New York-based organisation Human Rights Watch said 14 people had been arrested in connection with the planned demonstrations.
But a pro-government rally is now taking place in Green Square in the centre of the capital Tripoli, with reports of students arriving from outside the city.
The demonstrators have been shouting: "We are defending Gaddafi and the revolution!" and "The revolution continues!"
Apart from the square the city is said to be calm, with banks and shops open as normal.
Wednesday's unrest occurred in other cities. A newspaper connected to one of Libyan leader Col Muammar Gaddafi's sons, Libya al-Yawm, showed the police station in al-Bayda on fire.
