Kharkiv has borne the brunt of the Kremlin's ongoing offensive against the Ukrainian energy sector. Russia bombed the city early this Thursday with several waves of drone bombs.

EL PAÍS heard at least four unmanned vehicles that were able to cross the urban center for long minutes without being shot down first on their path from Russian territory. 350,000 people completely lost their electricity supply throughout the province as a result of this Thursday's attack. The Air Force reported that it intercepted 11 of 20 drones, an effectiveness rate of 50%. Until now, the average in the country has been 90%.
