KYIV: Russian drones struck infrastructure in the central Ukrainian city of Kryvyi Rih on Wednesday, forcing emergency power blackouts ​for more than 45,000 customers and disrupting heat supplies, military administration head Oleksandr Vilkul said.

“Please fill up on water and charge your devices, if you have the chance. It’s going to be difficult,” Vilkul said on the Telegram ‌messaging app.

Water ‌utility pumping stations ‌switched ⁠to ​generators ‌and water remained in the system, but there could be pressure problems.

The full scale of the attack was not immediately known. There was no comment from Russia about the strike.

Russia has repeatedly struck Ukraine’s ⁠power plants, substations and transmission lines with missiles and ‌drones, seeking to knock out ‍electricity and heating ‍and hinder industry during the nearly ‍four-year war.
