Chaos erupted in Serbia’s parliament on Tuesday with opposition lawmakers setting off smoke grenades and tear gas to protest the government and support demonstrating students.

At least three lawmakers were injured, with one in critical condition after suffering a stroke, further fueling political tensions in the landlocked Balkan country, which is located at the crossroads of Southeast and Central Europe.

Video footage from the assembly hall showed a clash first between lawmakers and later flares and smoke bombs being thrown. Serbian media said eggs and water bottles were also hurled. Hundreds of opposition supporters rallied outside the parliament building during the session.

But opposition parties said the ruling majority was also planning to approve dozens of other decisions. They said this was illegal and that lawmakers should first confirm the resignation of Vucevic and his government.

After the ruling coalition led by the Serbian Progressive Party (SNS) approved the agenda, some opposition politicians ran out of their seats towards the parliamentary speaker and scuffled with security guards.

Others tossed smoke grenades and tear gas, with black and pink smoke rising inside the parliament, which has also witnessed brawls and the throwing of water in the decades since the introduction of multi-party democracy in 1990.

As the session continued, ruling coalition politicians debated while opposition lawmakers whistled and blew horns.

Opposition deputies also held signs reading “general strike,” and “justice for the killed,” while outside the building protesters stood in silence to honor 15 people killed by a railway station roof collapse.

Parliament speaker Ana Brnabic accused the opposition of being a “terrorist gang.” The ruling coalition says Western intelligence agencies are trying to destabilize Serbia and topple the government by backing the protests.

The government has tried to evade scrutiny by downplaying the government’s culpability in the collapse at the station. At first, the government tried to ignore the protests, then began to use force and accused the protests of being infiltrated by foreign agitators. 

Some observers complained that the Vucic government’s failure to act and provide clear answers to the public is endemic to Serbia’s core institutional corruption.

Meanwhile, protest leaders called for a major rally in the capital Belgrade on March 15.
