The protesters are detained upon their attempts to block the streets of the city, a Sputnik correspondent said. Among the arrested are drivers who try to jam the roads.

Sargsyan, who served as the Armenian president from 2008 until recently, 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.
