Serbian President Aleksandar Vucic has vowed to launch a large-scale disarmament plan to remove hundreds of thousands of guns from the country, following back-to-back mass shootings in the Balkan country this week.
Serbian police are reported to have arrested the suspected gunman after eight people were killed and at least 10 injured in a drive-by shooting near Belgrade.
"We will do an almost complete disarming of Serbia," Mr Vucic said during a live broadcast, hours after the latest shooting.
The reported arrest comes after an hours-long manhunt through the night in the country's second mass shooting this week.
The drive-up shooting came a day after nine people were shot dead at an elementary school in the Serbian capital.
Near Mladenovac, an attacker armed with an automatic weapon opened fire from a moving vehicle before fleeing, state-run RTS television reported.
Police had been searching for the attacker after the shooting, with a heavy security presence and helicopters in the region.
Police had blocked the road leading to the villages of Malo Orasje and Dubona.
Worried relatives gathered outside the emergency medical centre in Belgrade where at least eight injured people were hospitalised, N1 television reported.
Health Minister Danica Grujičić briefly visited the centre. Interior Minister Bratislav Gašić called the shooting a "terrorist act", RTS reported.
The Serbian Honorary Consul to Ireland, Zivko Jaksic, told RTÉ's News at One that there was a shock in Serbian communities throughout the world following the recent shootings.
He said there is a certain amount of gangland violence in Serbia, or single acts where people are murdered or attempts are made, but what happened this week is "totally unpresidented, out of the blue".
He added that the Government had responded strongly, and despite strict laws on arms in the country, there are still a large number held illegally.
"Police are going to be cracking down on that.
"The shock is so enormous that the Government will have to react quite vigorously on that."
Serbia still reeling from school shooting
The Balkan nation is already recovering from a deadly school shooting on Wednesday, when eight students and a security guard were killed by a 13-year-old suspect at the Vladislav Ribnikar elementary school in downtown Belgrade.
Another six students and a teacher were wounded in that incident, while health officials said two injured individuals remain in critical condition.
While spring is normally a festive time in Serbia with people flocking outdoors, a three-day mourning period will begin today.
Mass school shootings are extremely rare in Serbia and Mr Vucic called Wednesday's tragedy "one of the most difficult days" in recent history.
In a national address after the school shooting, Mr Vucic proposed stricter gun control measures, including a two-year moratorium on issuing permits for firearms.
The Interior Ministry has appealed to all firearm owners to keep their guns locked in safes, warning that those who do not abide will have their weapons seized.
The Vladislav Ribnikar elementary school remained sealed off yesterday, with police guarding the entrance to the building.
Hundreds continued to flock to the school to pay their respects, placing flowers, toys and candles at a makeshift memorial.
People in the Croatian capital Zagreb and the Bosnian Serb administrative capital Banja Luka also lit candles and laid flowers for the victims.
Masses for the victims were held in Belgrade churches while the head of the Serbian Orthodox Church (SPC), Patriarch Porfirije, called the shooting a "catastrophe, the likes of which has never happened in our nation and our homeland".
In the Mladenovac region, a villager killed 13 relatives and neighbours in an April 2013 shooting.
