Ukraine's Chernihiv region came under mortar fire from Russian territory early on May 11.
Viacheslav Chaus, head of the Chernihiv Regional Military Administration, said this on Telegram, Ukrinform reports.
"Just an hour ago, at 06:00, our territory came under another mortar attack from the territory of the Moscow scum. The enemy is constantly doing this. Therefore, I have a big ask, especially for residents of border areas, please be careful," Chaus said.
He also warned of the danger of missile strikes and asked for air raid sirens not to be ignored.
