Ukrainian President Volodymyr Zelenskyy said Russian forces fired dozens of rockets and rockets into the southern city of Mykolaiv over the weekend, killing agricultural tycoon Oleksiy Vadaturskyi. Vadaturskyi owns Nibulon, which exported more than 5.6 million tons of wheat, barley, corn and other agricultural products to 38 countries last year. His wife, Raisa, also died in the bombings, Zelensky said. “Just such people, such companies, our Ukrainian south have guaranteed the world’s food security. That’s how it has always been. And it will be that way again,” Zelensky said on Sunday. “Russian terrorists should not even hope to be able to destroy Ukraine’s social and industrial potential and walk through the ruins.” RUSSIA CLAIMS 40 UKRAINIAN PRISONERS KILLED IN STRIKE WITH CHIMARES US, UKRAINE SUCCEEDS IN ‘BALANCED EXECUTION’ Nibulon confirmed Vadaturskyi’s death on Saturday, saying the businessman had stayed in his hometown of Mykolaiv to help the city after Russia invaded earlier this year. “The entire team of 7,000 people of the NIBULON company and the whole of Ukraine suffered an irreparable loss,” the company said in a statement.
