"He was taken out of the car, and with his eyes blindfolded he was driven in an unknown direction," Kotin wrote on the Telegram messaging app, adding there was no immediate word on Murashov's fate.Asked by Reuters for comment, a spokesperson for the IAEA said: "We have contacted Russian authorities and are requesting clarifications.""The IAEA sought clarification from the Russian authorities and has been informed that the director-general of the Zaporizhzhia Nuclear Power Plant was temporarily detained to answer questions," a spokesperson said without elaborating.The Zaporizhzhia plant has been a focal point of Russia's seven-month invasion of Ukraine, as Moscow and Kyiv accuse each other of shelling the facility, risking a nuclear disaster.In his Telegram statement, Kotin said Murashov "bears main and exclusive responsibility for the nuclear and radiation safety" of the plant and his detention "jeopardizes the safety of operation of Ukraine and Europe’s largest nuclear power plant"."
