Kyiv shuttered parliament on Friday for one day, citing a potential Russian missile attack after President Vladimir Putin issued a warning to the West by launching a new intermediate-range missile at Ukraine.
Vucic's ominous comment comes after Ukraine carried out its first strike on Russian territory with a US-supplied long-range missile on Tuesday - just days after the Biden administration gave Kyiv the green light despite fears it could escalate the conflict beyond control.
Russia's ballistic missile attack on Ukraine has prompted Kyiv to close its Parliament amid the ongoing war between the two nations.
On Friday, an air-raid warning was in effect for more than 10 hours in Kyiv Oblast, with air defence forces actively operating in the oblast.
