A serious accident at a high-voltage substation in Ukraine's Odesa region has caused emergency power outages in the regional capital, Ukraine's Prime Minister Denys Shmyhal said on Saturday.
"The situation is difficult, the scale of the accident is significant, it is impossible to quickly restore power supply, in particular to critical infrastructure," Shmyhal wrote on Telegram.
He said the substation had previously been damaged multiple times by Russian missile strikes.
