He said Russia would meet the goals of its “special military operation” and that Western arms supplies to Kyiv were prolonging the conflict. Russia’s foreign ministry announced sanctions against 32 officials and journalists from New Zealand for supporting what it called the country’s “Russophobic agenda”. Russian gas producer Gazprom has announced it has stopped supplying gas to neighboring Latvia, accusing it of violating supply terms.
