One person was killed and nine others including an eight-month-old baby were injured Sunday in a strike on a post office in Ukraine's second city Kharkiv, local authorities said.
The head of Kharkiv's regional administration, Oleg Synegubov, said a post office employee was killed.
The city of Kharkiv has been regularly targeted by Russian troops, who launched a major ground offensive in the region on May 10.
Russian President Vladimir Putin has said the offensive in Ukraine's northeast was intended to create a "buffer zone" to protect Russia's border Belgorod region from shelling.
On Saturday, seven people were also killed and nearly 40 injured in a Russian strike on Vilniansk, close to the regional hub of Zaporizhzhia.
