Greece has signed a deal with Ukraine to supply US-origin liquefied natural gas (LNG) to the country amid the crippling of its energy infrastructure from Russian strikes. Sunday’s agreement came as Volodymyr Zelenskyy visited Athens at the start of a European tour aimed at shoring up Ukraine’s defences and energy supply ahead of winter. The deal – to run from December until March 2026 – “marks an essential step in strengthening regional energy cooperation and European energy security”, said a joint statement from the Ukrainian president and the Greek prime minister, Kyriakos Mitsotakis, after they met. The deal would make it possible to “support Ukraine in the midst of a difficult winter”, they said. The deal came as Ukrainian energy infrastructure was damaged by Russian drone strikes overnight into Sunday in the Odesa region, Ukraine’s State Emergency Service said. A solar power plant was among the damaged sites.

Russia said on Sunday its forces had moved forward sharply in south-eastern Ukraine’s Zaporizhzhia region, taking two settlements as part of a major push aimed at seizing the whole region. The Russian defence ministry said its forces had taken Rivnopillya, which puts the southern town of Huliaipole in danger of being the target of Russian pincer movements, and that Russian forces had also taken Mala Tokmachka, just 9km (6 miles) from Orikhiv. “It is difficult to overestimate the importance of this village for the defence of Orikhiv,” said Yuri Podolyaka, one of Russia’s top war bloggers, adding that Mala Tokmachka was essentially “the gateway to Orikhiv”. There was no immediate comment from Ukraine.

Ukrainian forces struck a major oil refinery in Russia’s Samara region, along with a warehouse storing drones for the elite Rubicon drone unit in the partially Russian-occupied Donetsk region, Ukraine’s general staff said on Sunday. It said it had recorded explosions and a fire at the site of the strike on the Novokuibyshevsk refinery, but was still assessing the extent of damage. Russian officials did not immediately confirm the attacks.

Volodymyr Zelenskyy has announced a plan to clean up Ukraine’s energy sector after a $100m kickback scheme was alleged by anti-corruption investigators , in the worst scandal of his presidency. Jennifer Rankin and Luke Harding report that over the weekend the Ukrainian president announced an overhaul of key state energy companies including a complete change of management at Energoatom, the nuclear power operator at the centre of the alleged criminal scheme. Government officials, Zelenskyy said, were instructed “to maintain constant and meaningful communication with law enforcement and anti-corruption bodies. Any scheme uncovered in these companies must receive a swift and just response.”

A ceasefire in Ukraine is unlikely before the spring, Finland’s president has said , and European allies need to keep up support despite the Ukrainian corruption scandal. Europe would require “sisu’’ – a Finnish term for resilience – to get through the winter as Russia continued its hybrid attacks in Europe, Alexander Stubb told the Associated Press.

Greenpeace has said France is sending reprocessed uranium to Russia for treatment so it can be reused , despite Moscow’s war in Ukraine. The environment group said on Sunday that while it was legal, the trade was “immoral” as many nations seek to step up sanctions on Russia over its invasion. Greenpeace members on Saturday filmed the loading of about 10 containers with radioactive labels on to a cargo ship in the Channel port of Dunkirk, the NGO said. The consignment was the first of reprocessed uranium to be observed for three years, it said. France’s energy ministry and the French state-controlled energy company Electricite de France did not respond to questions from Agence France-Presse on the consignment or trade.

Ukraine is working to resume prisoner exchanges with Russia that could bring home 1,200 Ukrainian prisoners , Volodymyr Zelenskyy said on Sunday, a day after his national security chief announced progress in negotiations. “We are … counting on the resumption of PoW exchanges,” Zelenskyy wrote on X. “Many meetings, negotiations and calls are currently taking place to ensure this.”
