Ukraine’s energy minister warned households on Wednesday that planned blackouts could worsen in coming days and Russian forces could launch a new air attack ​to further disable power and heating networks.

Denys Shmyhal said well over 200 emergency crews were at work in the capital restoring heating to apartment buildings after a series of mass Russian attacks in January. Kyiv Mayor Vitali Klitschko said on Tuesday that more than 1,100 buildings remained without heating.

“The situation with energy ‌remains very ‌difficult. There is a risk that ‌timetables ⁠for ​power ‌cuts could get worse,” Shmyhal wrote on Telegram after a daily meeting of senior officials devoted to energy issues.

“This is linked to the last strike and the fact that the shortfalls in generation in the power system are still significant. And the Russians are preparing for ⁠new attacks on the energy sector in the coming week.”
