About 20 people were detained in Baku on Saturday when police dispersed an unauthorized opposition rally in Azerbaijan’s capital calling for the dissolution of parliament, RIA Novosti reported.

The rally, organized by the youth wings of the Musavat and the Popular Front opposition parties, chanted slogans: “Resign!” and “Freedom!”

The protests are linked to a video released in late September, purportedly showing a ruling-party MP offering a seat in parliament in return for a $1 million bribe.

The Baku City Prosecutor’s Office has launched criminal proceedings into the case on “fraud” charges.

The first protest rally was held on October 20, when about 40 opposition activists were detained.
