These are the key developments from day 1,401 of Russia’s war on Ukraine.

Here is where things stand on Friday, December 26:

Fighting

• Officials in Russia’s Krasnodar region reported a huge fire following a Ukrainian drone strike on two storage tanks holding oil products in the southern Russian port of Temryuk. The blaze spread across roughly 2,000 square metres (some 21,500 square feet).
• Long-range Ukrainian drones targeted oil storage facilities at Temryuk port, as well as a gas processing plant in Russia’s Orenburg region, Ukraine’s SBU security service said.
• Ukraine’s General Staff said its military also struck the Novoshakhtinsk oil refinery in Russia’s Rostov region using Storm Shadow missiles, triggering several explosions.
• The General Staff described the Russian refinery as a major supplier of oil products in southern Russia that supports Moscow’s military operations in Ukraine.
• Russia’s Ministry of Defence announced that its forces had taken control of the settlement of Sviato-Pokrovske in eastern Ukraine’s Donetsk region, according to reports from Russian state news agencies.

Regional security

• Poland sent fighter jets to intercept a Russian reconnaissance aircraft flying near its airspace over the Baltic Sea and said dozens of objects entered Polish airspace from Belarus overnight, warning the incidents during the holiday season may signal a provocation.
• Russia’s Ministry of Foreign Affairs accused the United States of encouraging what it called “piracy” in the Caribbean and Pacific Ocean by blockading Venezuela, while expressing hope that US President Donald Trump’s pragmatism could prevent further escalation.
• Moscow also reiterated its support for Venezuelan President Nicolas Maduro’s government and its efforts to safeguard national sovereignty amid threats by the US to remove Maduro from power.

Peace talks

• Ukrainian President Volodymyr Zelenskyy said he spoke with Donald Trump’s special envoy Steve Witkoff and son-in-law, Jared Kushner, for about an hour on how to end the war with Russia and “how to bring the real peace closer”.

• “Of course, there is still work to be done on sensitive issues,” the Ukrainian leader said. “But together with the American team, we understand how to put all of this in place. The weeks ahead may also be intensive. Thank you, America!”

• Russia believes negotiations with the US to end the war in Ukraine are making gradual progress, Russian Foreign Ministry spokeswoman Maria Zakharova said. She described the talks as slow-moving but advancing steadily.

Politics and diplomacy

• Kremlin spokesman Dmitry Peskov said President Vladimir Putin had sent the US president a Christmas greeting along with a congratulatory message.
•  Russia said it had put forward a proposal to France concerning Laurent Vinatier, a French researcher imprisoned under Russia’s foreign agent laws, adding that the next steps in the Frenchman’s case now rest with Paris.

Sanctions

• Russia’s target of producing 100 million tonnes of liquefied natural gas annually has been pushed back by several years due to international sanctions, the country’s Deputy Prime Minister Alexander Novak said in comments aired on state television.
