Several thousand people attended a further demonstration convened in Yerevan on 27 April by the Artarutiun opposition bloc to demand the resignation of President Robert Kocharian, RFE/RL\'s Armenian Service reported. The organizers postponed their planned march on the presidential palace from 27 April to 4 May, saying they will give the authorities a final chance to stage a nationwide referendum of confidence in Kocharian. They also stressed they did not want to exacerbate tensions on the eve of a 28 April discussion of the political situation in Armenia by the Parliamentary Assembly of the Council of Europe spring session in Strasbourg. Also on 27 April, the Armenian authorities deported Artur Vartanian, an Armenian-born U.S. citizen who served as a bodyguard to Artarutiun leader Stepan Demirchian, RFE/RL\'s Armenian Service reported. Vartanian was detained last week for participating in the ongoing series of protest demonstrations organized by Artarutiun. (RFE/RL)
