KYIV, Ukraine (AP) — Ukraine has halted Russian gas supplies to European customers through its pipeline network, almost three years into Moscow’s all-out invasion of its neighbor. A prewar transit deal expired at the end of 2024. Both Ukraine’s energy minister and Russia’s state-owned energy giant Gazprom confirmed on Wednesday morning that the gas flows had stopped. Until now, Russian natural gas had kept flowing through the country’s pipeline network to Europe under a five-year agreement even after Russia’s 2022 invasion. Before the war, Russia supplied nearly 40% of Europe’s natural gas through pipelines. By 2023, that figure was around 8% as users switched to liquefied natural gas from the U.S. and Norway.
