The group seized the police post in the capital, Yerevan, on July 17, demanding freedom for a jailed opposition figure, and took those inside hostage. The last of those hostages were released on Saturday.
After an exchange of fire before dawn Wednesday two of the gunmen surrendered and one police officer and two gunmen were wounded and taken to hospitals. Over 20 gunmen are believed to remain in the police station, the Associated Press reported.
Police spokesman Ashot Agaronyan said the gunmen took the paramedics hostage after they were called in to treat the wounded.
