In the evening, the demonstrations took place at the monument to Russia's Nicholas II, across the street from the residence of Serbian President Aleksandar Vucic in Belgrade's city center. Members of a Serbian far-right political party called Obraz joined the rally.
The reports indicated that the demonstrations blocked the street of King Milan. The more than 1000 participants unfurled a nearly 20-meter-long Russian tricolor flag, and chanted "Russia, Serbia."
From the loudspeakers installed at the monument were played the anthems of both countries. Authorities confirmed that the rally was held peacefully. Another rally was held on Monday as support to Russia in Montenegro.
During Montenegro's Monday demonstration nearly 100 gathered in front of an Orthodox church in the central city of Niksic.
Serbian President Vucic said that his country would not stand against the Russian military operation. The President noted that imposing sanctions against countries does not fit with Serbia's political and economic interests.
