Russian monopoly Gazprom said it had completely suspended gas supplies to Bulgarian company Bulgargaz and Polish PGNiG due to non-payment in rubles.
Gazprom's statement was quoted by the Russian news agency TASS.
It is noted that "in case of unauthorized withdrawal of Russian gas from the transit volumes to third countries, the supplies for transit will be reduced by this volume."
Meanwhile, Hungarian Foreign Minister Péter Szijjártó claimed that Russian gas continues to flow to Hungary as scheduled, despite the termination of supplies to Bulgaria.
On the previous day the Polish media reported that Russia was halting gas supplies to Poland.
In response, Polish Prime Minister Mateusz Morawiecki said he was sure that Poland was already able to fully replace Russian gas.
The Bulgarian Energy and Coal Ministry reported it had stopped supplying Russian gas as of 27 April.
