(ANSA-AFP) - MOSCOW, MAY 22 - Ukraine's occupied Zaporizhzhia nuclear plant has been cut off from the power grid again, its Russian administrators and the Ukrainian atomic agency said on Monday, a potentially dangerous incident that has become more frequent due to shelling. "Due to a high-tension line being cut, the plant lost its external electricity supply," the Russian administration wrote on Telegram, adding the causes of the outage were being investigated and that back-up diesel generators were keeping it working. Ukraine's nuclear agency Energoatom accused Russia of carrying out an attack on Monday morning that caused the power cut, saying it was the seventh instance of the plant entering "blackout mode" since Moscow's troops took control in March 2022. Energoatom said the generators had enough fuel reserves to last 10 days. "If it is impossible to restore external power to the plant during this time, an accident with radiation consequences for the whole world may occur," it warned. (ANSA-AFP).
