Mandatory Credit: National Assembly of the Republic of Serbia
A brawl broke out in the Serbian parliament in Belgrade on Friday night after opposition MPs brought out signs criticising the ruling party for its lack of reaction to a new law of religious freedom in neighbour Montenegro.
Dveri leader Bosko Obradovic and ally Ivan Kostic entered part-way through a session carrying banners reading "Vucic and Milo - the twin brothers" and "Serbia, why are you silent?"
Social Democratic Party of Serbia (SDPS) MPs Vladimir Marinkovic, Aleksandar Martinovic and Defence Minister Aleksandar Vulin responded with fists.
After a brief scrap, National Assembly President Maja Gojkovic called for calm before eventually adjourning the session.
The Dveri MPs were "dissatisfied" at the failure to respond to the new law and the arrest of pro-Serbian opposition MPs disrupting Montenegro's parliament.
