The Zaporizhzhia nuclear power plant in southern Ukraine was temporarily cut off from the power grid on Thursday after fires damaged the last operating transmission line, state nuclear company Energoatom said. Ukraine and Russia have traded blame for bombings and other damage at the facility, which is Europe’s largest nuclear power plant. Russian forces initially seized control in March, but allowed Ukrainian staff to continue operations.

We cannot afford to waste any more time,” IAEA Director General Rafael Mariano Grossi said in a statement on Thursday. “I am determined to personally lead an IAEA mission to the plant in the coming days to help stabilize the nuclear safety and security situation there.” RUSSIAN AND UKRAINIAN ALLEGED SPIES FOR KREMLIN ARRESTED AT BASE IN ALBANIA AFTER GUARDS DROWNED IN CHEMICAL AGENT President Biden spoke with Ukrainian President Volodymyr Zelensky on Thursday, and the two leaders called on Russia to return control of the plant to Ukraine, according to a White House statement.

The fourth and final transport line lost connection twice on Thursday but was back up and running, the IAEA said.
