Ukraine's energy agency has warned a nuclear power plant currently controlled by Vladimir Putin's troops is in danger of "hydrogen leakage and sputtering of radioactive substances".
Energoatom - a state-run agency which runs all four of Ukraine's nuclear facilities - revealed that two power units at Zaporizhzhia have been reconnected to the country's grid.
But despite the positive development, the Russian military's presence means there are "serious risks" looming.
