Armenian opposition leaders appealed at an unsanctioned rally in Yerevan on 14 May for the population to participate in a planned 21 May march to the presidential palace to demand the resignation of President Robert Kocharian, RFE/RL\'s Armenian Service reported. Some opposition leaders are concerned at a recent decline in attendance at ongoing protest rallies. They attribute that decline to the repeated postponement of \"decisive action\" to force Kocharian\'s resignation and to the attempts, which collapsed on 13 May, to defuse tensions between the opposition and the three-party governing coalition by means of negotiations. Meanwhile, Armenian human rights activists picketed the Prosecutor-General\'s Office on 14 May for the second consecutive day to demand the release of 14 opposition activists against whom criminal charges have been brought in connection with their participation in a mass protest against Kocharian in Yerevan on 12-13 April that was violently dispersed by police, RFE/RL\'s Armenian Service reported.
