KYIV, Ukraine (AP) — Ukraine’s nuclear power provider says Russian forces blindfolded and detained the head of Europe’s largest nuclear power plant hours after Moscow illegally annexed a swath of Ukrainian territory. In a possible attempt to secure Moscow’s hold on the newly annexed territory, Russian forces seized the director-general of the Zaporizhzhia Nuclear Power Plant, Ihor Murashov, around 4 p.m. Friday. Russian President Vladimir Putin on Friday signed treaties to absorb Luhansk, Donetsk, Kherson and Zaporizhzhia regions of Ukraine, including the area around the nuclear plant. The International Atomic Energy Agency said Saturday that Russia told it that “the director-general of the Zaporizhzhia nuclear power plant was temporarily detained to answer questions.”
