"They want to deprive Hungary of its sovereignty," Zakharova said after Serbian authorities discovered explosives near the Turkstream gas pipeline from Serbia to Hungary.
"They are doing this in different ways, politically, by trying to interfere in internal affairs and elections," Zakharova said.
"Economically, by imposing decisions that harm the economy and well-being of the Hungarians, and via energy, they try to prevent Hungary from receiving high-quality and reasonably priced resources."
Earlier on Sunday day, Serbian President Aleksandar Vucic said he told Hungarian Prime Minister Viktor Orban by phone that authorities found explosives near the pipeline which supplies Russian gas.
