Ukraine’s special forces said ⁠they attacked two crucial natural gas plants in the Arctic about 3,000km (1,800 miles) from the Russian-Ukrainian border. Both lie in the heartland of Russian gas production: Novy Urengoy is Russia’s unofficial gas capital, ⁠located in the Yamal-Nenets region in north-western Siberia. The other plant is in the Purovsky district of Yamal-Nenets. A Ukrainian statement described the ‌two plants as “crucial for the gas condensate industry … Previously, this was considered an absolutely safe area away from the front ​for the aggressor.”

Fire Point, a Ukrainian company that makes deep-strike weapons including the Flamingo cruise missile, posted: “Guess who just travelled over 3,300km and successfully hit the target?” Volodymyr Zelenskyy, the Ukrainian president, praised the strikes for their effect on the Russian ​economy. The Russian regional governor confirmed the attack and said the damage was being assessed. About 80% of all natural gas in Russia is extracted in the Yamalo-Nenets region, according to the Interfax news agency.

Ukrainian forces also targeted Novorossiysk, a Black Sea port in Russia’s Krasnodar region. The attack hit the Russian naval base, including a terminal used to load oil, military port facilities, and warships carrying cruise missiles, Zelenskyy said.
