Armenia has ended the state of emergency that was imposed in the capital after clashes between protesters and police left eight dead.
Emergency rule was declared after 11 days of protests
Army vehicles began leaving Yerevan before midnight on Thursday.
The authorities have confirmed that more than 100 opposition activists are being held on charges of causing unrest and plotting a coup.
The clashes on 1 March took place when police tried to end more than a week of mass protests against election results.
The presidential poll gave victory to the current Prime Minister, Serzh Sarkisian. The opposition says the results were falsified.
The number of arrests has been rising steadily throughout the month, as the Armenian authorities round up the people they believe were responsible for the violence.
Those detained so far include several members of parliament and a former foreign minister. The opposition has accused the government of trying to crush political dissent in Armenia.
Outgoing President Robert Kocharian has warned the opposition that any attempts to hold unauthorised protests will not be tolerated.
A new law was passed this week giving the authorities the right to ban demonstrations, if it is believed they will pose a threat to public order.
But the opposition leader, Levon Ter-Petrosyan, has vowed to continue his campaign to overturn the election results.
The opposition insists it had the right to defy what it describes as a violation of people's freedom and has said it will find a way to work around the legislation.
