The National Human Rights Organization is calling for an urgent change to the law, after 30 people were questioned by police.
They are all members of the Damascus Declaration, which calls for political reform in Syria. 20 of them are still being held, hours after they were asked to come in for questioning. 10 others were released soon afterwards.
The NHRO says the promised law which will allow people to freely “organize political life” now needs to be passed as a matter of urgency.
