Russia’s latest drone and missile attacks on Ukraine’s energy infrastructure caused widespread power outages across the country on Thursday, killing at least three people, including a 7-year-old girl, officials said. Ukrainian authorities described the strikes as “systematic energy terror” aimed at disrupting daily life and lowering morale ahead of winter.

The attacks involved over 650 drones and more than 50 missiles, according to President Volodymyr Zelenskyy. Centralized Ukrainian infrastructure, which supplies water, heating, and sewage services, was disrupted nationwide, leaving millions without essential utilities. Children aged 2 to 16 were among the 17 injured in the strikes.

Ukrainian Prime Minister Yuliia Svyrydenko condemned Moscow’s actions, saying the goal was “to plunge Ukraine into darkness” while promising to maintain essential services. She called for stronger air defense systems, tougher sanctions, and increased international pressure on Russia to halt the attacks.

In southern Zaporizhzhia, 17 people were injured, including a 2-year-old girl. Rescuers recovered a man from building rubble, but he later died. A second victim was also reported in the region. Meanwhile, a 7-year-old girl succumbed to injuries in Vinnytsia in central-west Ukraine.

In western Lviv, two energy facilities were damaged near the Polish border. Poland temporarily closed regional airports in Radom and Lublin and scrambled military aircraft as a precaution in response to the cross-border threat, according to the Polish Air Navigation Services Agency.

The attacks come amid nearly four years of conflict following Russia’s full-scale invasion of Ukraine, with Moscow targeting power, weapons production, and critical infrastructure.
