Russian strikes killed four people across Ukraine on September 26 while Ukraine hit Russian oil refineries with long-range drones, leaving 10 people dead in total, according to the Associated Press. The bloodshed came as US President Donald Trump said he hoped Ukraine's leader would "settle" with Vladimir Putin.

Two women died under the rubble of their home in Zaporizhzhia, regional officials said, and two people were killed in a separate attack on Sumy. Drone strikes on Kyiv's districts injured four people, while two were hurt in a warehouse fire in Boryspil.

Russia's defence ministry said its Kyiv strike hit a data centre supporting mobile internet and Starlink communications. Ukraine continued to target Russian oil and industrial facilities, keeping up its campaign against the country's energy infrastructure.

President Volodymyr Zelenskyy wrote that "Russia is escalating every single day" and urged partners to respond strongly. More than four years after Russia's full-scale invasion began, the intensifying aerial war shows no sign of slowing.
