More than 300 people were evacuated from their apartments overnight following a Ukrainian drone attack on the capital of the Rostov region in Russia, the acting governor has said.
The Russian defence ministry said air defence units destroyed 13 Ukrainian drones over the Rostov region overnight. It did not say how many drones were detected.
"An unexploded (drone) shell was discovered in one of the apartments," Rostov region's acting governor, Yuri Slyusar, said on the Telegram messaging app. "As a precaution, 320 residents of the building are being evacuated."
The attack damaged several apartment buildings in the city of Rostov-on-Don, he added. Three people, including a child, were lightly injured.
Rostov-on-Don Mayor Alexandr Skryabin said residents were relocated to a school while bomb disposal experts were removing the shell.
Reuters could not independently verify the reports. There was no immediate response from Kyiv.
Meanwhile, a civilian has been killed as a result of an overnight Russian airstrike on the city of Bila Tserkva in the Kyiv region, the governor of the Ukrainian region said.
"A body of a man was discovered while firefighters were putting out a fire at a garage complex that got on fire as a result of the attack," Mykola Kalashnyk, the governor, said on Telegram.
"Damage has been reported across multiple parts of the city. Windows in several multi-storey residential buildings were shattered, and fires broke out in [several] areas."
Both sides deny targeting civilians in their strikes during the war that Russia launched with a full-scale invasion on Ukraine in 2022.
About 2,000 North Korean troops killed in Russia deployment - Seoul spy agency
Meanwhile, around 2,000 North Korean soldiers deployed to help Russia fight Ukraine are estimated to have been killed, Seoul's spy agency said today, according to a politician.
Seoul's National Intelligence Service (NIS) said in April "the number of war dead was at least 600. But based on updated assessments, it now estimates the figure at around 2,000," politician Lee Seong-kweun told reporters after a briefing from the spy agency.
South Korean and Western intelligence agencies have said the North sent more than 10,000 soldiers to Russia in 2024 - primarily to the Kursk region - along with artillery shells, missiles and long-range rocket systems.
Mr Lee said that the NIS believed that Pyongyang planned to deploy another 6,000 soldiers and engineers to Russia and that 1,000 had already arrived.
"It is assessed that out of the recent third deployment plan of 6,000 troops, around 1,000 combat engineers have arrived in Russia," Mr Lee said.
Earlier this year, Moscow's Foreign Minister Sergei Lavrov said that North Korea would send builders and deminers to the Kursk region.
North Korea only confirmed it had deployed troops to support Russia's war in Ukraine in April and admitted that its soldiers had been killed in combat.
Since then, North Korean leader Kim Jong Un has met with the families of soldiers killed fighting for Russia against Ukraine and offered condolences for their "unbearable pain".
State media has run images of an emotional Mr Kim embracing a returned soldier who appeared overwhelmed, burying his face in the leader's chest.
The leader was also seen kneeling before a portrait of a fallen soldier to pay his respects and placing medals and flowers beside images of the dead.
Russia and North Korea signed a military deal last year, including a mutual defence clause, during a rare visit by Russian President Vladimir Putin to North Korea.
