SARAJEVO, Bosnia and Herzegovina

Thousands of protesters in the Serbian capital of Belgrade are gathering Friday for a massive anti-government against President Aleksandar Vucic, following months of unrest for alleged government negligence.

The Students in Blockade movement announced that the protest Saturday would begin at 4 p.m. local time (1500GMT) in front of parliament.

Organizers said on Instagram that a detailed timetable for marches across the city would be released later. The post included an image of the parliament building, which authorities closed for the weekend.

The protests began in November after a concrete roof collapsed at the Novi Sad train station, killing 15 victims and injuring dozens. The accident ignited nationwide outrage, with critics blaming the government for failing to maintain critical infrastructure and ignoring safety warnings.

Demonstrators have since gathered almost daily, demanding accountability and systemic reforms. The protests have gained significant momentum, particularly among students and young activists, many of whom are marching to Belgrade on foot and bicycle from parts of Serbia.

- Vucic warns against unrest

Vucic rejected speculation Friday that he would concede to demands for a transitional government.

“As long as I am alive, there will be no transitional government,” Vucic declared.

He urged everyone to avoid inciting unrest and for demonstrators not to compromise the country’s peace and stability.

While labeling the protest “illegal,” Vucic insisted that Serbia remains “an exceptionally democratic country.”

He contrasted Serbia’s response to Germany and France, claiming that instead of resorting to force, authorities would work to ensure a peaceful rally.

“We will do our best to guarantee the safety of all participants and protect institutions such as Pioneers’ Park and the Serbian Parliament,” said Vucic.

He warned, however, that anyone disturbing the peace would face strict punishment, and those attempting to attack the rally would be immediately arrested.

- Security concerns, government countermeasures

Authorities have stepped up security ahead of the protest.

Vucic described “disturbing” reports of truncheons and Molotov cocktails found in a vehicle in Belgrade, though he urged police to use force only if “absolutely necessary.”

A group identifying themselves as “Students 2.0,” set up camp in Pioneers’ Park, near the presidency building, demanding the government allow them to return to classes.

In what many see as an effort to suppress the turnout, the government suspended nationwide railway services, citing security concerns -- a move critics argue is meant to limit participation in the protest.

Vucic reaffirmed that violence would not be tolerated and that organizers would be held responsible for any incidents.

“State authorities will ensure security and work to protect both protest participants and all other citizens,” he said.

He claimed that the protests are disrupting investments and economic growth in Serbia, citing reports from global financial authorities.

- Arrests on suspicion of planning attacks on institutions

Authorities have arrested six people in connection with the protests. Acting on orders from the Higher Public Prosecutor’s Office in Novi Sad, members of the Interior Ministry detained those suspected of preparing to act against the constitutional order and security of Serbia. The charges also include inciting a violent change in the government.

Vucic warned that additional arrests could be made, stating that any individuals attempting to enter Serbia with the intent of destabilization would also be detained.

- Investigation into “negotiations with the Army”

Vucic announced an investigation into allegations that some protest leaders have been in discussions with military officials, hinting at possible coup attempts.

“The army is doing its job in accordance with the law, and no one needs to worry about it,” he said, adding that a state of emergency would not be enacted at this time.

Responding to speculation that his rule is nearing an end, Vucic dismissed those claims.

“We will talk about that the day after tomorrow. Those who think they can overthrow institutions should think again,” he said.

Despite rising tensions, he reiterated his call for peace.

- A defining moment for Serbia’s political future

The demonstrations have expanded beyond the Novi Sad train station collapse, evolving into a broader movement against corruption, government mismanagement and democratic backsliding.

Protesters - including students, educators, and farmers -- are demanding greater transparency and institutional accountability.

As Serbia braces for one of the largest anti-government protests in its recent history, opposition groups insist the movement will remain peaceful. With rising tensions and increasing government crackdowns, however, the coming days could prove to be a pivotal moment for Serbia’s political landscape.
