Russian state media reported on Sunday that Ukrainian long-range drones set fire to the Kstovo refinery in Nizhny Novgorod oblast overnight. The reports came soon after a major strike on another large refinery in Samara oblast, which is owned by the Russian state energy company Rosneft.

The Kremlin said Kyiv is "simply ignoring" US wishes, days before the US midterm elections. The source does not say what those wishes were or who in Washington voiced them, beyond describing pressure from Donald Trump.

A ceasefire in the occupied town of Oleshky is due to end late on Sunday, according to the report.
