Russia's Defence Ministry said on Thursday that Ukrainian forces had attempted to seize the Russian-controlled Zaporizhzhia nuclear plant in southern Ukraine.
In a statement, the ministry said that up to 60 Ukrainian troops had crossed the Dnipro river, which divides territory held by the two sides, in boats at 6:00 a.m. local time. It called the operation a "provocation" aimed at disrupting a planned visit by International Atomic Energy Agency inspectors to the nuclear plant.
The ministry said that "measures had been taken" to destroy the opposing troops, including use of military aviation.
Reuters could not immediately verify the reports.
