The protesters have gathered on the streets in response to calls on social media. It was not clear who is organising the events, although government officials says the demonstrations are the work of political opponents.
Protesters said they see Vucic as an autocrat and his Serbian Progressive Party as corrupt and instrumental in what they say was a fraudulent election.
Demands posted online by one group of students included dismissing the election commission, the media regulator and top editors of the state RTS TV for allegedly failing to facilitate a free and fair vote.
“I think that something needs to change and I am here to express my discontent with the current situation,” he said.
On Monday, Vucic said that “everyone has a right to be unhappy with the election results.”
“It is fine as long as it is peaceful,” Vucic said.
