One person was killed in Russian drone attacks on a port district in Ukraine’s southwestern Odesa region early Wednesday, the regional governor said.

The night-time attacks lasted three hours and targeted the Izmail district, Oleg Kiper said on Telegram.

The Danube river port of Izmail, which borders NATO member Romania, has become a main export route for Ukrainian products following Russia’s withdrawal from a UN-brokered grain deal in July.

“Unfortunately, one person died,” said Kiper, adding that it was an agricultural worker who was seriously injured and died in hospital.

“Destruction and fires were recorded in several settlements,” he added, saying that port and agricultural infrastructure had been damaged, including administrative buildings.
