The UN’s Office for the Coordination of Humanitarian Affairs (OCHA) announced Sunday that a safe passage operation is underway in Ukraine, where civilians from the Azovstal steel plant in Mariupol are being evacuated to Zaporizhzhia, according to OCHA Spokesperson Saviano Abreu.

The UN and the International Committee of the Red Cross are coordinating the safe passage of women, children and the elderly who have been stranded in Azovstal for nearly two months, the statement reads. Evacuees are expected to receive humanitarian support, including psychological services in Zaporizhzhia, Abreu said.

UN OCHA’s operation began on Friday alongside a joint UN/ICRC convoy traveling from Zaporizhzhia and reached the steel plant in Mariupol on Saturday morning.
