On April 14, Armenia's ruling Republican Party nominated Serzh Sargsyan for the post of prime minister.
Around 6,000 gathered in Armenia's capital on Monday in protest at what the opposition calls a power grab by former president Serzh Sarksyan and several people were injured in scuffles with police. "They've already called the house", she said.
Demonstrators have vowed to keep protesting round the clock.
Some protesters chanted "Armenia without Serzh" and "Serzh is a liar". The parliament is expected to vote Tuesday on the matter.
As of Monday, several streets in central Yerevan remain blocked by hundreds of protesters, with Pashinyan, calling for civil disobedience including paralysing traffic, striking, and boycotting classes in universities. "Our goal right now is to prevent Serzh Sarkisian from becoming the country's leader for a third time without violence and the use of force", said Pashinian.
Earlier this week, two opposition lawmakers set off smoke flares in parliament to protest plans for Serzh Sarkisian to become prime minister. Some protesters began to build barricades with trash bins and benches.
Having previously played down suggestions he would run again for political office, Sargsyan announced on 11 April that he would seek the position of Prime Minister, now the most powerful post in the country. After Sarkisian was first elected president in February 2008, 10 people died in bloody clashes between police and supporters of the defeated opposition candidate.
