Hungary's Prime Minister Viktor Orbán says his country will challenge the European Union's plan to end Russian energy imports in court

An impasse over Russian oil and imminent US sanctions has put Serbia at loggerheads with its traditional ally in Moscow. Added differences over Russian gas supplies and Serbia's arms trade have ramped up the tensions, with Serbian President Aleksandar Vucic trading barbs with the Kremlin.

Ukrainian Foreign Minister Andriy Sybiha said at the start of a meeting on Ukraine and defense cooperation that Kyiv needs to overcome what will be a “very difficult, very tough winter.”

Standing near the mangled exterior of his thermal power plant, the 53-year-old production manager described the now familiar job of a Ukrainian energy worker: swiftly patching up the workplace during another season of intense Russian air strikes.

Trump's warning about Russian gas dependence proved prophetic as Europe now imports 57% of gas from U.S. instead of Russia after Moscow's 2022 energy cutoff backfired.

Millions of Ukrainians are enduring cold temperatures and darkness after a wave of Russian attacks against energy facilities caused widespread power outages across the country.

Workers at a DTEK thermal power plant say the facility is facing its worst level of destruction since the start of Russia’s full-scale invasion, following one of the latest strikes targeting Ukraine’s energy infrastructure.

Hungary said on Saturday it had obtained an indefinite waiver from U.S. sanctions to use Russian oil and gas, but a White House official reaffirmed that the exemption was for one year only.
