Serbia's largest-ever rally sees 325,000 protest against government
Hundreds of thousands of people descended on Serbia's capital on Saturday to protest over the deaths of 15 people in a railway station collapse.
While the government put attendance at 107,000 across Belgrade, an independent monitor said 325,000 - if not more - had gathered, making it Serbia's largest protest ever.
The Novi Sad collapse last November has galvanised anger towards the government and President Aleksandar Vucic. Demonstrators blame corruption and corner-cutting for the loss of life.
They believe the disaster reflects more than a decade of governing by the Progressive Party of Vucic - who closely associated himself with the station's recent renovation.
Despite multiple resignations - and Vucic's insistence that he is going nowhere - the protests have only continued to grow.
"We just want a country that works," law student Jana Vasic told the BBC in the growing crowd in Belgrade.
"We want institutions that do their jobs properly. We don't care what party is in power. But we need a country that works, not one where you don't get justice for more than four months."
Republic Square - just one of the four meeting points around Serbia's capital for the "15th for 15" protest - was full to overflowing on Saturday.
Some took refuge on the plinth of Prince Mihajlo's statue - the traditional spot for Belgraders to meet, the equivalent of Eros in London's Piccadilly.
Others queued up along the road in front of the National Museum, stretching all the way back to Students' Square.
The other meeting points were every bit as crowded ahead of the planned rendezvous in front of the National Assembly.
The Public Meeting Archive said 275,000-325,000 had attended the protest - "with the possibility that the number was even higher".
Addressing the nation on Saturday, Vucic praised the police, adding that he was proud that "we managed to preserve the peace".
He said that he "understood" the protesters' message, and that "we will have to change ourselves".
Vucic has described the student protests as "well-intentioned". But he had less flattering words for opposition parties, labelling them members of a "criminal cartel". He accused them of attempting to force the formation of a "fraudulent interim government".
Borko Stefanovic does not deny that the opposition parties are looking for the establishment of a "government of experts".
The deputy president of the Party of Freedom and Justice describes it as the "only rational way out" of the political crisis, which would establish the conditions for fresh elections.
Like other opposition leaders, Stefanovic says that free elections are not currently possible due to the Progressive Party's domination of the media and state institutions.
But this is not one of the students' demands. They are simply calling for the truth behind the Novi Sad disaster to be established.
As law professor Miodrag Jovanovic puts it "they are asking for the things I've been lecturing about - the rule of law, respect for the constitution, and the responsibility and accountability of public officials".
Whatever happens during the "15th for 15" protest, it seems unlikely that the students will relent until they receive some satisfactory answers.
