Beirut: Security forces on Thursday arrested blogger Razan Gazzawi, icon of the 11-month uprising in Syria, along with rights activist Mazen Darwish and 12 others, opposition figures said.

Human rights lawyer Anwar Bunni said Razan was arrested in an early afternoon raid on the Syrian Centre for Media and Freedom of Expression, which is located in central Damascus and is headed by Darwish.

"We at the Syrian Centre for Legal Studies condemn these arrests and call on Syrian authorities to immediately release them," Bunni said in a statement.

Earlier, opposition figure Louay Hussain, an opponent of Syrian President Bashar Al Assad, told Reuters that activist Yara Badr was also detained in the raid.

Darwish has been active in documenting human rights violations committed by Syrian forces in the revolt against Al Assad.

He was detained last year after taking part in a protest to demand the release of political prisoners.
