Representatives of opposition started to gather on the central square of the Montenegrin capital, Podgorica, right in front of the government building. According to local media reports and activists, about hundreds people are already there.
A few buses are parked near the site of the event. The protesters carry Serbian and NOVA political party flags.
Protests against Montenegro's entry into NATO have been continuing for several months now. On December 2 the NATO member-states foreign-ministers sent an official invitation to Podgorica to start negotiating on entering NATO.
