The governor of Russia's Belgorod region, Vyacheslav Gladkov, said that Ukrainian forces attacked a village near the border on Friday, but no casualties resulted. Gladkov's Saturday statement revealing the episode wasn't accompanied by evidence nor resulted in any statements by Ukrainian authorities. 

"In Belgorod district, 21 artillery shells and three cluster munitions from a multiple-launch rocket system were fired at the village of Zhuravlevka," Gov. Vyacheslav Gladkov said.

It was only within this past week that both Kiev and the Biden administration confirmed initial deliveries of the munition which is banned in over 120 countries, given that it kills indiscriminately and its bomblets sometimes remain in the ground unexploded, leaving them a deadly hazard for years.

Belgorod, a southern Russian region along the Ukrainian border, has been subject of cross-border Ukrainian attacks for over the past year throughout the conflict. This has most often come in the form of drone attacks or cross-border shelling, most often targeting energy or other civilian infrastructure. 

Ukraine's defense ministry has pledge to only use cluster munitions to dislodge enemy Russian positions, and not against civilians, Reuters had noted earlier this week.
