Russian strikes on a hospital in the Ukrainian border city of Sumy killed nine people Saturday, as President Volodymyr Zelensky condemned Moscow for "waging war on hospitals".
Sumy lies just across the border from Russia's Kursk region, where Kyiv launched a shock offensive on August 6, aimed in part at creating a "buffer zone" inside Russia.
"Russia hit one of the city's hospitals with Shahed drones," Zelensky wrote on Telegram and regional authorities said the toll had risen to nine dead and 12 injured.
The attack comes as Zelensky is pressing Kyiv's Western allies to allow the use of long-range precision weapons to strike deep inside Russia.
"Everyone in the world who speaks about this war must pay attention to what Russia is targeting. They are waging war on hospitals, civilian objects, and people's lives," the president said.
Ukrainian Prime Minister Shmygal said the attack was "more evidence of Russia's war crimes".
Zelensky posted photos of smoke pouring from windows above the destroyed entrance to the hospital, rescuers carrying patients down the stairs and treating two policemen lying on the ground.
On Saturday morning, three drones attacked the regional capital city and two hit the hospital, Ukraine's air force said.
A first strike was followed by another around an hour later on Saturday morning, officials said, apparently targeting the rescue operation to maximise casualties.
Ukrainian Interior Minister Igor Klymenko wrote on Telegram that the first strike "killed 1 person" and damaged several floors of the hospital.
"During the evacuation of patients, the enemy struck again", Klymenko wrote.
Russia has destroyed or damaged least 1,736 medical facilities in Ukraine since its February 2022 invasion, Human Rights Watch reported in July.
A Russian missile struck a Kyiv children's hospital in July and a maternity hospital in Mariuopol was bombed in March 2022.
Ukraine's National Police condemned the twin strikes as a "cynical attack" that killed one policeman and injured another.
Regional prosecutors said the first attack took place at around 7:35 am (0435 GMT) and the second about an hour later.
Images of the scene posted by officials showed body bags lying on the pavement outside the four-storey building with a destroyed entrance and the roof partially ripped off.
Officials have not named the hospital, but its director Volodymyr Potseluyev told Suspilne media outlet that the hospital's admission department, casualty department and fourth floor were destroyed.
He said seriously injured patients had been transferred to intensive care units at other hospitals.
Regional authorities said the strikes also hit a residential area and posted images of flats with broken windows.
Dobrobat, a volunteer group that helps repair damaged homes, wrote on Facebook that its volunteers were working at the scene when the second strike came.
It posted a video showing thick smoke, explosions and people rushing to take shelter as sirens wailed.
"People are just lying on the street dead," a volunteer said, filming himself on his phone.
"We survived due to a miracle as we went into the entranceway of a building", the unnamed volunteer said.
Ukraine's air force reported shooting down 68 Russian attack drones out of 73 in multiple regions overnight, including Sumy.
It said it also downed two out of four cruise missiles launched overnight by Russia.
In the central city of Kriviy Rig, rescuers pulled another body from the rubble of a police office building struck by a missile on Friday, regional governor Sergiy Lysak said, taking the toll to four.
In the southern Kherson region, partly occupied by Russia, a 75-year-old woman and an 83-year-old man were killed by shelling over the last 24 hours, regional governor Oleksandr Prokudin said on Telegram.
In Russia's Belgorod border region, governor Vyacheslav Gladkov said a local resident was killed Saturday morning by a drone attack.
