Russia and Ukraine have targeted each otherās energy facilities in tit-for-tat attacks, leaving hundreds of thousands of people without power, officials from both countries said, as the worldās attention has shifted to the US-Israel war on Iran.

In Ukraineās southern region of Odesa, Russian ā attacks ā late on Tuesday killed ā one person and wounded another, emergency services said.

Alexander Drozdenko, governor of Russiaās Leningrad region, said the fire was being brought under control and that no casualties had been reported.
Ukraine has stepped up drone attacks on Russian oil refineries and export routes over recent weeks in an attempt to weaken Russiaās war economy.
