Protesters are calling for the resignation of the Serbian president and the mayor of Novi Sad over the accident that killed 15 people.
Thousands of Serbians have gathered in the capital Belgrade to protest against President Aleksandar Vucic and his ruling Serbian Progressive Party (SNS), which they blame for last month's railway roof collapse that killed 15 people.
The meeting, which is one of the biggest in recent years, was called on Sunday by university students and farmers' associations and was held at the Slavija square in Belgrade.
It started with 15 minutes of silence as a tribute to as many people were killed After the concrete roof of the recently renovated Novi Sad station collapsed on November 1.
Fourteen people, aged between six and 74, were killed that day and a 15th died in hospital a few weeks later.
Prosecutors arrested 13 people in connection with the case, including a government minister whose later release raised doubts about the integrity of the investigation.
Leaders of opposition parties and people have come to the streets again and again saying that the accident was caused by corruption and nepotism in the government. The ruling coalition denies the charges, and Vucic said those responsible should be held accountable.
The protesters on Sunday evening turned on the lights of their phones and shouted “Vucic, thief!” Others carried signs that read “We are all under the roof” and “You have blood on your hands”.
“We came here to say 'Stop' to everything that has been happening since 2012 (when Vucic's party took power),” said Aleksa, 30, an IT specialist from Novi Sad. “We want to see an end to corruption and nepotism.”
Many are calling for the resignation of the Serbian president and the mayor of Novi Sad, and for those found guilty of the crime to be brought to justice. They are also calling for the charges against the protestors to be dropped, and for the protesters to be prosecuted.
Prominent Serbian actors took part in the protests, with actor Bane Trifunovic describing Sunday's rally as a “festival of freedom”.
Small meetings were also held in the cities of Nis and Kragujevac.
In order to end the protests, the government authorities in the last weeks have promised various financial aid to the youth. The students – and some citizens who are supporting them – will continue to protest, saying that their demands have been partially met.
Despite the ongoing protests, Vucic on Sunday inaugurated a section of the newly built highway in central Serbia.
Vucic said he would not budge from the opposition to the transitional government and accused his opponents of using students to try to seize power.
“We will beat them again,” he said. “They (opponents) don't know what to do but use somebody's children.”
The protests, which have lasted for several weeks, have taken place amid opposition to Vucic's law. He also said that he wanted to take Serbia into the European Union but faced accusations of restricting democratic rights instead of advancing them.
