A Russian strike on Wednesday killed at least 13 people and injured 63 in Ukraine’s southeastern city of Zaporizhzhia.
The guided explosion left bodies strewn across a road alongside injured residents.
Public transport was also damaged in the strike.
Prosecutors in the region said 63 people had been injured in the Russian strike.
Rescue work had been completed at the spot.
High-rise apartment blocks were damaged along with an industrial facility and other infrastructure, Ukraine’s prosecutor general office said on Telegram.
The debris hit a tram and a bus with passengers inside, it added.
As emergency workers tried to resuscitate a man, raging flames, smoke and burnt cars could be seen in the background.
Russian troops had used two guided bombs to hit a residential area, the regional governor Ivan Fedorov told reporters.
At least four of the injured were rushed to hospital in serious condition, Fedorov said, adding that Thursday would be an official day of mourning.
“There is nothing more cruel than launching aerial bombs on a city, knowing that ordinary civilians will suffer,” President Volodymyr Zelenskyy said on X, urging Ukraine’s Western allies to step up pressure on Russia.
“The protection of lives in Ukraine must be supported. Only through strength can such a war be ended with a lasting peace,” Zelenskyy said on X.
Regional authorities reported further explosions after the first strike hit.
Fedorov said Russian troops shelled the town of Stepnohirsk, south of Zaporizhzhia, killing two people.
Two residents were pulled alive from underneath rubble.
Russia regularly carries out air strikes on the Zaporizhzhia region, which its forces partially occupy, and its capital.
Moscow claims to have annexed the Ukrainian region along with four others including Crimea.
Public broadcaster Suspilne also reported two people killed and 10 injured in attacks on several centres in the southern region of Kherson, also partially occupied by Russian forces.
