A third operation is under way to evacuate civilians from the Ukrainian port city of Mariupol and the besieged Azovstal steel plant, U.N. Secretary-General Antonio Guterres told the U.N. Security Council on Thursday.
The United Nations and International Committee of the Red Cross (ICRC) have so far helped nearly 500 civilians flee the area during two operations in the past week. Guterres declined to give details on the new operation "to avoid undermining possible success."
