Oleksiy Vadatursky, founder and owner of agriculture company Nibulon, and his wife were killed in their home, Mykolaiv Governor Vitaliy Kim said on Telegram.
Headquartered in Mykolaiv, a strategically important city that borders the mostly Russia-occupied Kherson region, Nibulon specializes in the production and export of wheat, barley and corn, and has its own fleet and shipyard.
President Volodymyr Zelenskiy described Vadatursky's death as "a great loss for all of Ukraine", saying the businessman had been building a modern grain market involving a network of transhipment terminals and elevators.
