Last year was the deadliest for civilians in Ukraine since 2022 as Russia intensified its aerial barrages behind the front line, according to the UN Human Rights Monitoring Mission in the country.
A Russian drone crashed into a home in Ukraine's northeastern Kharkiv region overnight, killing a father and his three small children and seriously wounding their mother who is 35 weeks pregnant, officials said on Wednesday.
The strike completely destroyed the house and set it on fire, with the family trapped under the rubble, according to the Kharkiv regional prosecutor’s office.
The 34-year-old father and his three children, twin boys aged two and their one-year-old sister, were killed, while rescue workers pulled the mother alive from the rubble, prosecutors said.
She sustained blast injuries, a traumatic brain injury, burns and hearing loss, they said.
The drone that struck the Kharkiv town of Bohodukhiv was identified as a Geran-2, a Russian-made version of an Iranian Shahed drone.
"We lost what is most precious — our future," Bohodukhiv mayor Volodymyr Bielyi wrote on his Facebook page.
"There are no words to console the family; there is no prayer that could heal the heart of a mother who has lost her children."
Bielyi said the mother is fighting for her life in hospital and announced three days of mourning, when national flags will be lowered and all entertainment and organised public events will be cancelled.
"We will endure. We will remember. We will never forgive this horror on our land," Bielyi wrote.
Bohodukhiv had a pre-war population of 15,000. It is located some 22 kilometres from the Russian border. It wasn't immediately clear whether there was any Ukrainian military infrastructure near the house.
"Each such Russian strike undermines trust in everything being done through diplomacy to end this war, and again and again proves that only strong pressure on Russia and clear security guarantees for Ukraine are the real key to stopping the killings," Ukrainian President Volodymyr Zelenskyy said on social media.
Ukraine has accused Russian forces of committing countless war crimes since the start of the war and European institutions have made efforts to hold Russia accountable.
The International Criminal Court in The Hague has multiple outstanding arrest warrants for Russian officials for war crimes. They include President Vladimir Putin, who is accused of personal responsibility for the abductions of children from Ukraine.
Zelenskyy said late on Tuesday that Ukraine is making "many changes" in the way it fights Russia's aerial attacks, especially with short-range air defences. Training and replenishing new troops are also key issues, he said.
Ukraine has been short-handed against Russia's bigger army, though Moscow's forces have made only creeping progress in their invasion.
Wide-scale desertions and 2 million draft-dodgers are among a raft of challenges for Ukraine, Defence Minister Mykhailo Fedorov said last month.
Zelenskyy has also pressed Western partners to provide more sophisticated air defence systems and missiles to help defend Ukraine.
Ukraine's Air Force says Russia launched 129 long-range drones at Ukraine last night.
Meanwhile, a Ukrainian drone attack caused a fire at an industrial plant in the city of Volgograd, authorities said.
Volgograd regional Governor Andrei Bocharov said that drone fragments also damaged an apartment building.
Eight Russian airports briefly suspended flights overnight because of drone attacks, officials said.
During the almost four years since Russia launched its full-scale invasion and despite a new push over the past year in US-led peace efforts, Ukrainian civilians have endured constant aerial attacks.
Last year was the deadliest for civilians in Ukraine since 2022 as Russia intensified its aerial barrages behind the front line, according to the UN Human Rights Monitoring Mission in the country.
The war killed 2,514 civilians and injured 12,142 in Ukraine in 2025, up 31% compared to 2024’s figures, it said.
