KYIV (Reuters) -Ukraine said on Friday it had struck a Russian oil refinery and a microchip factory in a huge drone attack that caused fires at the refinery's production facilities and an oil pumping station.
Russia said hours earlier that its forces had repelled an overnight drone attack, but four industry sources confirmed to Reuters that one of Russia's oldest refineries had been struck in the city of Ryazan southeast of Moscow overnight.
