Russia claimed on Friday that it had successfully launched strikes against Ukraine's air defenses, which were protecting critical military infrastructure targets.
At a press briefing in Moscow, Defense Ministry spokesman Igor Konashenkov said the mass strike was carried out on Thursday night using high-precision weapons.
"All assigned objects are hit," Konashenkov said.
Ukraine, for its part, launched a series of attacks in response, including on Russia-controlled areas in the Zaporizhzhia region.
According to the Russian state-run news agency, Ukraine's armed forces struck the port of Berdyansk with long-range StormShadow missiles provided by the UK, leaving at least nine people injured.
