Overnight Russian air strikes have killed at least four people, including three young children in Ukraine's north-eastern Kharkiv region, local officials have said. Regional head Oleh Synegubov reported that two boys, both aged two, a one-year-old girl, and a 34-year-old man died after a drone hit their house in the town of Bohodukhiv. Furthermore, a 35-year-old pregnant woman and another 73-year-old woman were injured in the attack. This devastating strike comes as Moscow has resumed its aerial campaign following a week-long hiatus, which had been requested by Donald Trump during a bitter cold spell across Ukraine. The town of Bohodukhiv has faced almost daily assaults in recent days, raising concerns about the safety of its residents. Local authorities have declared a state of emergency due to the crippling energy crisis exacerbated by ongoing attacks, which have left many without heating amid frigid temperatures.
