Ukrainian President Volodymyr Zelenskyy said there is new damage to Ukraine's energy infrastructure as Kyiv imposed nationwide limits on power usage.
Meanwhile, close followers of developments in Ukraine will be watching to see what happens after Russian president Vladimir Putin imposed martial law on four illegally annexed regions in Ukraine: Kherson and Zaporizhzhia in the south, and Donetsk and Luhansk in the east.
Zelenskyy called on men in what Ukraine regularly describes as "temporarily occupied areas" of southern and eastern Ukraine to resist being recruited into Russia's armed forces. "Please avoid it as much as you can. Try to leave the occupied territory," he said.
Kherson is particularly interesting right now after the Russian-installed administration there began a mass evacuation of civilians Wednesday.
Russian officials said residents should leave the area of Kherson to the west of the Dnipro river and should travel on to Russian regions, warning that Ukraine was about to renew its counteroffensive to retake Kherson, saying military hardware and personnel were being amassed near the region.
Russian TV footage on Wednesday showed crowds gathering and waiting to cross the Dnipro river. Ukraine said Russia was using "propaganda" to scare Kherson residents and coerce them to flee.
