Ukraine's state nuclear energy agency on Tuesday accused Russia of detaining two senior employees at the Russian-controlled Zaporizhzhia nuclear power plant in southern Ukraine.

Ukraine's state nuclear energy agency on Tuesday accused Russia of detaining two senior employees at the Russian-controlled Zaporizhzhia nuclear power plant in southern Ukraine.

In a statement on social media, Energoatom said Russian forces on Monday "kidnapped" the head of information technology Oleg Kostyukov and the plant's assistant general director Oleg Osheka and "took them to an unknown destination".

Energoatom called on International Atomic Energy Agency (IAEA) chief Rafael Grossi "to make every effort" to secure their release.

Russian troops captured the Zaporizhzhia nuclear power plant at the beginning of March, in the early days of Russia's invasion of Ukraine.

Ukraine has recently accused Russia of detaining several of the plant's employees.

Last week Energoatom said Russia detained and mistreated the plant's deputy director general for human resources, Valeriy Martyniuk.

The energy agency has not released updates on Martyniuk's situation since then.

In late September, the agency said Russia detained the chief of the power station, Ihor Murashov, for several days before releasing him on October 3.

The nuclear plant -- Europe's largest atomic facility -- is located in Russian-held territory of Ukraine's Zaporizhzhia region, which Moscow claims to have annexed together with three other territories in Ukraine: Donetsk, Lugansk and Kherson.

Moscow and Kyiv have traded blame for months over shelling near the Russian-held facility, sparking fears of a nuclear disaster and spurring calls to de-militarise areas around atomic facilities in Ukraine.

-Destroyed power stations-

President Volodymyr Zelensky said Tuesday Russian forces had "destroyed" a third of Ukraine's power stations in repeated strikes that targeted energy infrastructure.

"Since October 10, 30 percent of Ukraine's power stations have been destroyed, causing massive blackouts across the country," Zelensky said on Twitter, adding there was "no space left for negotiations with (President Vladimir) Putin's regime". 
Several regions of Ukraine, including the capital Kyiv, were experiencing power cuts after multiple strikes targeted energy facilities, local officials and agencies said Tuesday.

Many settlements in Zhytomyr region, west of Kyiv, and parts of Dnipro city in central Ukraine were without electricity, while power was restored to the southern city of Mykolaiv after strikes overnight.
