A Russian drone attack overnight damaged four power facilities near the southern Ukrainian city of Odesa, leaving more than 29,000 customers without electricity on Sunday morning, the region's governor and power firm DTEK said.

Axar.az reports, citing Reuters, hardest hit was the port city of Chornomorsk, just outside Odesa, where residential houses and administrative buildings were also damaged, said Oleh Kiper, the governor of the broader Odesa region, on the Telegram messaging app.

“Critical infrastructure is operating on generators,” Kiper said, adding that one person had been injured as a result of the attack.
