UNITED NATIONS -- UNITED NATIONS (AP) — President Donald Trump said Tuesday that he believed Ukraine could win back all territory lost to Russia, a dramatic shift from the U.S. leader’s repeated calls for Kyiv to make concessions to end the war.

The Afipsky refinery in southern Russia caught fire overnight as Ukraine continues to strike its enemy’s energy infrastructure, exacerbating fuel shortages.

Russia's spring and summer offensives this year have failed to meet their goals, Ukraine's military chief Oleksandr Syrskyi said, adding that Russia was firing twice as much artillery as Ukraine on the battlefield.

Russia’s ban on petrol exports is now extended until the end of the year as shortages continue to hit the domestic market and spread across the regions. Kyiv says that in less than two months, Ukrainian forces struck 85 high-value targets in Russia.

Belarus is proposing to build a nuclear power plant in the east of the country that could supply electricity to Russian-controlled parts of Ukraine, President Alexander Lukashenko said on Friday. Lukashenko put the idea to Russian President Vladimir Putin at Kremlin talks in Moscow.

The president posted on Truth Social after he met with Ukrainian President Volodymyr Zelenskyy on the sidelines of the United Nations General Assembly in New York.

US President Donald Trump has said Kyiv can "win all of Ukraine back in its original form", marking a major shift in his position on the war with Russia. In a post on his Truth Social platform, he said Ukraine could get back "the original borders from where this war started" with the support of Europe and Nato, due to pressures on Russia's economy.

Russia expanded its list of banned UK nationals on Friday in response to what it said was London's continued confrontational course on Ukraine and "cynical anti-Russian adventures."
