05:02 AM EDT, 08/25/2025 (MT Newswires) -- Crude oil prices climbed on Monday following Ukrainian attacks on Russia over the weekend and an improved outlook due to a potential U.S. interest rate cut.

Brent crude at last look rose 0.4% to US$68.02 and West Texas Intermediate crude gained 0.5% to US$64/b.

Ukraine launched a drone attack on Russia on Sunday that cut the capacity of a reactor at one of Russia's power plants, Reuters reported Monday, citing Russian officials.

The attack also sparked a blaze at the Ust-Luga fuel export terminal, the officials said. Meanwhile, a fire at Russia's Novoshakhtinsk refinery sparked by a previous Ukrainian drone attack was burning for the fourth day on Sunday, the acting governor of the region said in the report.

"Given the success that Ukraine is having with its targeting of Russian oil infrastructure ... the risks for crude oil are shifting to the topside," Reuters quoted IG market analyst Tony Sycamore as saying.

Risk appetite among investors also improved following signals of a potential interest rate cut from U.S. Federal Reserve Chair Jerome Powell. The Fed is scheduled to meet next month.
