Russia has struck a high-rise apartment block in the north-east Ukrainian city of Kharkiv, killing at least three people and injuring 22 more, say local officials.
The attack on the residential building was carried out using guided glide bombs, the city's mayor said.
Ihor Terekov said Russia had attacked at least four districts in the city during the daytime attack.
The attack comes as fighting intensifies in the country's east with Russian troops encircling and closing in on the largely destroyed town of Vuhledar.
Shortly after Tuesday's blitz in Kharkiv, Ukraine's President Volodymr Zelenksy issued a statement on X calling on allies to help "stop the terror".
He is in New York to address the UN General Assembly's annual congress, having arrived on Monday reiterating Ukraine's need for timely US military assistance.
"There is much discussion now at the UN General Assembly about collective efforts for security and the future. But we just need to stop the terror. To have security. To have a future," Zelensky said.
Meanwhile, in Kharkiv, officials said the block that was hit had previously been struck at the start of the war.
"It was almost repaired, all the windows were put in, insulated, and prepared for the heating season. The enemy hit it a second time with a KAB [glide bomb]," said Kharkiv Mayor Terekov.
Russia has increasingly been using glide bombs in recent months - Soviet-era bombs fitted out with wings and satellite navigation aids. They are cheap, destructive, and are said to have been key to Russia's effort to capture further ground in Ukraine.
They were used in May in attacks in Kharkiv, while military analysts also note that they appear to have been used for the first time in Zaporizhzhia city on Sunday night.
Ukrainian officials said Russia conducted seven airstrikes with KAB glide bombs, injuring at least 21 civilians in the attacks on 13 residential buildings and two educational facilities.
Zaporizhzhia officials also said Russia had conducted another strike on the south-eastern city on Monday night, which killed one person and injured at least four others, including two children.
Russian forces have made serious advances in Ukraine's east and are closing in on Vuhledar, a coal-mining town on the southern part of the Donbas front line. The Russians have been trying to seize the town since the beginning of their full-scale invasion.
On Monday, Russian military bloggers were reporting that Moscow's troops had entered the outskirts of the town in the Donetsk region. Ukraine's military has mentioned only a number of attempts to capture its positions in Vuhledar.
Meanwhile, Russian forces have also recently advanced near Hlyboke, Kupyansk, and Pokrovsk, according to the US-based think tank the Institute for the Study of War.
The war tracking group said Ukrainian forces had recently advanced in the Kursk region.
