Russia fortifies Zaporizhzhia nuclear reactors amid Ukrainian offensive.
Russian troops have fortified the Zaporizhzhia Nuclear Power Plant's nuclear reactors in preparation for a possible Ukrainian counteroffensive. The fortifications include sandbag fighting positions on the roofs of several reactors. The move increases the chances of damage to the plant's safety systems if fighting takes place around it. The heaviest fortifications have been erected in the southern Zaporizhzhia region, which sits along the strategically vital Sea of Azov and in between the Kherson and Donetsk regions. Ukrainian troops have been training with Western forces for months in preparation for its looming offensive.
