More than 10,000 anti-government protesters have rallied in Armenia's capital.
Opponents of President Serzh Sargsyan have several demands, including the release of their incarcerated colleagues and snap elections.
Their leader, former President Levon Ter-Petrosian, says revolts in the Arab world have inspired the protest movement, but is vowing any change in government will be peaceful.
That represents a change of tactics for the combative Ter-Petrosian, who in earlier protests warned of a forceful overthrow.
Thursday's rally in Yerevan is the latest in a wave of demonstrations that began in February on the third anniversary of the 2008 violent suppression of a protest after a disputed presidential election.
