Ukrainian drone attacks on Russian oil refineries have reportedly reduced the country's oil processing capacity by around 30 per cent, as peace talks between Moscow and Kyiv resumed in Abu Dhabi with US involvement.
According to Reuters, citing sources, Ukrainian attacks disrupted operations and triggered emergency situations at nine of Russia's 35 major refineries over the past week.
The renewed attacks, which have intensified since late October, have affected Russia's oil refining sector amid ongoing efforts to negotiate an end to the war.
Meanwhile, US Secretary of State Marco Rubio said there was still "a lot" of work to be done following the first day of resumed peace talks between Ukraine and Russia.
The talks in Abu Dhabi involved US envoys Steve Witkoff and Jared Kushner, as Washington seeks what it describes as a "final end" to the war.
Rubio described the first day of discussions as "very productive" and said the aim was to expand the negotiations to include Europe.
US President Donald Trump had earlier said Washington was seeing a "very strong inclination" from both sides to end the conflict, adding that they were "tired of fighting".
A US official also claimed that Moscow and Kyiv were privately showing some flexibility over a possible territorial exchange ahead of the talks, described as the first serious peace negotiations since February.
Speaking to CBS's 60 Minutes, Trump said Ukraine would likely "end up with a different shape" following a potential agreement.
