Residents of the border communities in Sumy Oblast suffer daily shelling from nearby Russian forces. Ukrainian troops regularly fight off Russian sabotage groups conducting raids across the border.
Sumy Oblast was liberated from Russian occupation in April 2022.
Ukraine has built up its fortifications in Sumy Oblast in recent months and authorities have ordered evacuations from the region due to increasing attacks.
