The armed group that seized the building of a police and Interior Ministry Forces unit in Yerevan has set free one of the six hostages.

"We have gotten in touch with Jirair Sefilian [the leader of the Founding Parliament opposition group whose followers are involved in the hostage situation] and he suggested that one hostage be released. We set free the police officer with a medical condition. He has an allergy," Varuzhan Avetisian, a member of the armed group, told the local media.

"We are ready to resist a possible storm of the building by the police," Avetisian said.

He also said their demands were unaltered - release of Sefilian, resignation of the Armenian president and formation of a new government.
