Ukrainian attacks on Russia have killed at least nine people, while Russian attacks on Ukraine have killed at least five, according to officials in both countries.
The exchange of strikes comes amid signs both Moscow and Kiev are increasing the scale and intensity of attacks on each other, nearly four-and-a-half years into the war.
Civilian casualties in Ukraine have soared this year, as Russia has ramped up its use of hard-to-intercept long-range missiles, according to UN data.
Kiev has meanwhile launched waves of retaliatory strikes on Russia, including on energy facilities and retail warehouses, in an effort to pressure Moscow into negotiations on ending its offensive.

A separate drone attack on Russia's Saratov region bordering Kazakhstan killed two people, while three were killed in a Ukrainian drone strike on a car in Russia's Udmurtia region — more than 1,000 kilometres from the front line, the region's acting governor Olga Abramova said.
In Ukraine, Russian strikes killed two people in the eastern region of Dnipropetrovsk, and at least one person each in the southern regions of Zaporizhzhia and Kherson, according to regional authorities.
A separate Russian strike destroyed a postal terminal in the northern Kharkiv region, killing a postal worker, the mail operator Nova Poshta said.
