Aleksandar Vucic said in Moscow on Tuesday it was "obvious there is increase of tension in the Balkans, and attempts of an overall destabilization of relations."

The Prime Minister of Serbia spoke with reporters on the side-lines of a sitting of the Business Council of Serbia and Russia, and added that "somebody is making a lot of effort" to destabilize relations in the Western Balkans.

According to the Beta agency, Vucic then stated that he "knows, but won't say" who these "forces" are - but that he thought it was "plenty obvious."

"It's enough to look at the situation in our surroundings and to be completely clear. Why would I speak about it publicly, I have no intention, it's enough that I know, and the government knows, and is taking steps," said Vucic.

He added that "they are attempting to spread this to Banja Luka, Sarajevo, and Belgrade."

Vucic said that "Serbia will do everything to preserve peace and stability in the region; this is its priority goal."

"If anyone needs peace and stability, its Serbia, and Serbia will know how to secure it," said he.
