Ukraine's ambassador to the International Atomic Energy Agency (IAEA) Yevhenii Tsymbaliuk claimed that Russian forces wanted to cause electricity blackouts in southern Ukraine by shelling its Zaporizhzhia nuclear complex, and called for an international mission to the plant this month.

"We will use all possible channels of diplomacy to bring the IAEA and UN closer to conducting this mission," Tsymbaliuk told reporters in Vienna on Monday. "We really need it urgently, as soon as possible, I would say not later than the end of this month."
