Is the fall of Pokrovsk inevitable? Is Trump losing patience with Putin? Will sanctions against Russian oil giants hurt Putin? Ukraine is working to resume prisoner exchanges with Russia that could bring 1,200 Ukrainians home, President Volodymyr Zelenskyy says, a day after his national security chief announced progress in negotiations. "We are counting on the resumption of POW exchanges," Zelenskyy wrote on X on Sunday.

Is Trump losing patience with Putin? Will sanctions against Russian oil giants hurt Putin? Russian and Ukrainian troops have fought battles in the ruins of Pokrovsk, a transport and logistics hub in eastern Ukraine, with Ukraine's military reporting fierce fighting under way in a part of the city that was key for Kyiv's front-line logistics. Ukrainian President Volodymyr Zelenskyy said he visited troops fighting near the eastern city of Dobropillia, where Ukrainian forces are conducting a counteroffensive against Russian troops. Russia struck civilian energy and port infrastructure in a massive overnight drone attack on Ukraine's southern region of Odesa, the region's governor said in a post on the Telegram messaging app, adding that rescuers extinguished fires and there were no casualties.

How is Russia replenishing its military? What is a'coalition of the willing'? How China forgot promises and'debts' to Ukraine How are Europe, the US pulling apart on Ukraine? A Ukrainian drone attack killed three people and injured 16 near the town of Foros on the Crimean Peninsula, the Russian-appointed head of Crimea, Sergei Aksyonov, wrote in a post on Telegram. Russia's Ministry of Defence said the attack occurred "using strike drones equipped with high-explosive payloads", in a resort area "where there are no military targets whatsoever".

Russia has made gains in Ukraine's Donetsk region before President Vladimir Putin's high-stakes meeting with his United States counterpart Donald Trump in Alaska, raising fears that it may have increased its leverage amid talks aimed at ending the war. In advance of Friday's summit in Anchorage, Moscow's army pounded away at Ukraine's industrial heartland, attempting to seize the flashpoint town of Pokrovsk, a key highway and rail junction in eastern Donetsk, after repeated attempts to breach its defensive line during the week. As Putin and Trump prepared to meet, battlefield analysis site DeepState said that Pokrovsk was partially encircled. In recent days, Russian forces had reportedly seized the village of Yablunivka and the settlement of Oleksandrohrad – both in Donetsk. Ukrainian President Volodymyr Zelenskyy, who has rejected Putin's demands that Kyiv withdraw from the remaining 30 percent of Donetsk that it still controls, played down the Russian advances, saying on X that his forces were "countering" and "increasing the pressure" on the "occupier".

Ukraine's military has said it struck an oil refinery in Russia's Saratov region in an overnight drone attack, causing explosions and destruction, according to an army statement, as daily aerial exchanges intensify with diplomatic momentum to end the war in play. Saratov's governor said on Sunday that one person was killed and several residential apartments and an industrial facility were damaged, but did not mention the oil refinery being struck. "[Ukrainian] drones are targeting … deeper into Russian territory [than] in the past, where previous attacks have been focused on the line of contact in the south and the western parts of Russia," said Al Jazeera's Osama Bin Javaid, reporting from Moscow. It is still unclear whether Ukraine's claims that it hit a refinery are true, he added. Ukraine's military also said on Sunday that it had taken back a village in the Sumy region from the Russian army, which has made significant recent gains there.

Ukrainian drone strikes have killed at least three people and wounded two others overnight in western Russia, regional governors said, as a fire broke out at an oil refinery in central Russia after it was hit. One woman was killed and two others wounded in an attack on an enterprise in Penza, the region's governor, Oleg Melnichenko, wrote on Telegram on Saturday. The second death of an elderly man happened inside a house that caught fire due to falling drone debris in the Samara region, Governor Vyacheslav Fedorishchev posted on Telegram. In the Rostov region, a guard at an industrial facility was killed after a drone attack and a fire in one of the site's buildings, acting Rostov Governor Yury Slyusar said. "The military repelled a massive air attack during the night," destroying drones over seven districts, Slyusar posted on Telegram.

There is a realistic chance that one of the UK's largest oil refineries can be converted into a hub for green chemicals, sustainable fuels and plastics, Scotland's first minister says. Grangemouth oil refinery, which is being shut down by its UK and Chinese owners PetroIneos this year with the loss of 400 jobs, could become a world leader in low carbon chemicals and green fuels, John Swinney told media on Wednesday. The refinery's closure, after 100 years of production, is expected to hit up to 2,000 jobs in the east of Scotland. Trade union leaders and policymakers see Grangemouth as a casestudy in ensuring the transition from oil and gas is fair and just. Swinney said workers and local businesses faced "enormous difficulties".

Ukrainian shelling in the southern Russian city of Belgorod has killed two people and a drone attack caused a fire at a Russian oil refinery south of Moscow, officials have said, while Russian authorities claimed to have thwarted a new attempt by saboteurs to cross the border. Saturday's attacks occurred as Russians entered the second day of voting in a presidential election that is all but certain to extend Vladimir Putin's rule by another six years. A man and a woman died in the attack, and three other people were wounded, regional Governor Vyacheslav Gladkov said on the Telegram messaging app. It marks the latest exchange of long-range missiles and rocket fire in the Russia-Ukraine war. Five people were also wounded when a Ukrainian drone hit a car in the village of Glotovo, some two kilometres (1.25 miles) from the Ukrainian border, Gladkov said.
