UN Secretary-General Antonio Guterres has appealed to all concerned to "exercise common sense and reason and not to undertake any actions that might endanger the physical integrity, safety or security" of the Zaporizhzhia Nuclear Power Plant.

"I am calling on the military forces of the Russian Federation and Ukraine to immediately cease all military activities in the immediate vicinity of the plant and not to target its facilities or surroundings," he said in a statement on Thursday.
