The participants of rallies against Armenian ex-President Serzh Sargsyan's candidacy for the post of prime minister started to block the central streets late on Monday.
The policemen were pushing the protesters to the sidewalks, several people were taken to custody.
On Saturday, Armenia's ruling Republican Party nominated Sargsyan for the post of prime minister. On Monday morning, protesters blocked bridges, streets and underground stations protesting Sargsyan's candidacy. The parliament is expected to vote on the issue later in the day.
Sargsyan, who served as the Armenian president since 2008, had to step down due to presidential term limits. Armen Sarkisian was inaugurated as the new president on April 9 and became the first Armenian head of state who was elected by the parliament since the country switched from a presidential to a parliamentary system of government. Sargsyan's nomination for prime minister is largely regarded as an attempt to stay in power, since the newly amended constitution transferred some of the presidential powers to the head of the government.
