On Sunday, supporters of the Serbian opposition, who disagree with the results of the recent snap elections, surrounded the National Assembly in Belgrade, climbing the steps and trying to break down the doors, a Sputnik correspondent reported.
Police also used tear gas against a crowd of demonstrators who tried to break into the building. Later, police dispersed protesters from the square within minutes and set up a cordon.
"There is internal legislation, there are electoral bodies, there are also observers who did not record any violations that could cast doubt on the legitimacy of the elections that took place. In addition, there are processes and attempts by third forces, including from abroad, to provoke similar unrest in Belgrade," Peskov told reporters.
The Serbian leadership is capable of taking all measures to ensure security in the country, the official said, adding that Russia does not interfere in Serbia's sovereign affairs.
"As for our cooperation, it really has very broad prospects in a variety of areas," the official added.
Rallies have been taking place since December 18 by the opposition bloc Serbia Against Violence that opposes the outcome of the recent elections. On the evening of December 24, demonstrators tried to break into the city hall building, using flagpoles to break the door and smash windows.
