One civilian was killed and four others injured in Russian shelling overnight on Ukraine's Sumy region on the border between the two warring countries, the local Ukrainian administration said on Sunday.
"During the night and morning, the Russians carried out 18 shellings of border territories and settlements of the Sumy region. 47 explosions were recorded," the administration said on Telegram.
It said nine districts of the region were under attack.
Ukraine's air force said in a separate statement it had destroyed eight out of eleven Russian attack drones used overnight.

The Sumy region borders Russia's Kursk region, where Ukrainian forces launched a major cross-border incursion on August 6. Russian troops, meanwhile, continue to press towards the strategic hub of Pokrovsk in eastern Ukraine.
