Anti-government protesters have taken to the streets of the Syrian capital Damascus for a second day running but their demonstration was quickly quashed by security forces, witnesses said.
Around 100 people, mainly relatives of political prisoners, gathered in Marjeh Square on Wednesday calling for the release of their loved ones and an end to emergency laws.
Government supporters and police armed with batons urged the demonstrators to go home, before arresting four people, witnesses told the Reuters news agency.
On Tuesday some 40 to 50 people gathered after midday prayers in the Al Hamidiya area near the city's Umayyad Mosque in a rare show of dissent against Bashar al-Assad's regime.
Al-Assad, who succeeded his father as president in 2000, has said there is no chance of unrest elsewhere in the region spreading to Syria. The country has been ruled by al-Assad's Baath Party since 1963.
