Kyiv forces hit Russia's Kursk region that borders Ukraine with dozens of drones, killing an elderly woman, injuring nine people and sparking fries in several buildings in the region's administrative centre, Russian authorities said yesterday.

The Russian defence ministry, which releases data only on how many drones its forces destroy not how many Ukraine launches, said 109 drones were downed over the Kursk region overnight.

"Kursk has been subjected to a massive enemy attack overnight," the Kursk region administration said in a post on Telegram messaging app. "Unfortunately, an 85-year-old woman died."

A multi-storey apartment building was damaged in result of the drone attack, with several flats catching fire, acting mayor of Kursk, Sergei Kotlyarov said on Telegram. Residents have been evacuated to a nearby school, he added.

The region's administration posted photos of a multi-storey apartment building with blown out windows and fire damage to the facade.

Meanwhile, the Kremlin said yesterday that there is no clear outline of a US-Russia deal on Ukraine for now, but that there is political will to move in the direction of an agreement.
