Twelve miners have been killed by a Russian drone strike in eastern Ukraine, the country's largest private energy firm has said. DTEK reported that the attack targeted a bus carrying workers in the eastern Dnipropetrovsk region. This incident is part of a series of attacks, including a drone strike on a maternity hospital, leaving many injured and raising alarms about safety amidst ongoing military conflicts, particularly while Russia had previously assured not to strike civilian areas during the harsh winter.
