Nine were injured in Kharkiv overnight on May 30 amid a Russian drone attack on the city, local authorities reported.
"Specialized services are heading to the scene of the incidents," Kharkiv Oblast Governor Oleh Syniehubov said in a Telegram post.
Two 16-year-olds were injured, Syniehubov said, adding that residential buildings have been damaged in the drone attack.
Russia has intensified drone and missile attacks against Ukraine despite peace talks between Kyiv and Moscow in Istanbul on May 16.
The talks in Turkey were largely inconclusive. Russia reiterated maximalist demands that Ukraine hand over Crimea and eastern oblasts.
The two sides were able to agree to a 1,000-for-1,000 prisoner exchange, which was carried out between May 23 and 25.
Russian President Vladimir Putin refused President Volodymyr Zelensky's invitation to meet face-to-face in Istanbul. Instead, Russia sent a delegation of lower-level officials led by Putin's aide, Vladimir Medinsky.
Russia has refused a ceasefire and instead insisted it would provide Ukraine with a peace memorandum shortly after the May 16 talks. Ukraine and Russia are slated to hold another round of peace talks on June 2.
Meanwhile, Kyiv is still awaiting Russia's proposed ceasefire memorandum, Ukrainian Defense Minister Rustem Umerov said on May 28.
Kharkiv Oblast in Ukraine's northeast is a regular target of Russian missile, drone, and glide bomb attacks from across the border or Russian-occupied territories.
Russia has regularly targeted civilian infrastructure in aerial attacks against Ukraine since the start of its full-scale war in February 2022.
