There were numerous fires on agricultural land in eastern Ukraine in early July, when the region was under intensive military attack by Russia, according to an analysis of satellite images by The Yomiuri Shimbun and outside experts.
At most, more than 100 fires broke out in a single day in the region, the analysis found. In one case, the burned land totaled 45 hectares.
"The fires were likely caused by the conflict with Russian forces. They are dealing a significant blow to Ukrainian agriculture," a military expert said.
