BULGARIA-RUSSIA-UKRAINE-ENERGY-CONFLICT-GAS

A employee works near gas pipes at the gas compressor station of Bulgartransgaz in Ihtiman, on May 5, 2022, a week after the halt of Russian gas supply to Bulgaria. The halt of Russian gas has left companies -- big and small -- scrambling as they fear insecure deliveries and rising prices. Since its invasion of Ukraine soured its international relations, Moscow insists Gazprom customers must pay in rubles rather than US dollars or euros, leading the Russian energy giant to cut deliveries to Bulgaria and Poland on April 27.
