The head of the Russian National Defense Control Center, Mikhail Mizintsev, said on Sunday, that the Russian Defense Ministry has urged UN, OSCE, and Red Cross representatives to assist with the humanitarian operation to evacuate civilians from Ukraine's Mariupol.

"To fulfill this task [evacuation], we are also sending an official appeal to the UN, the OSCE, the International Committee of the Red Cross and other international organizations, inviting their representatives to accompany this humanitarian operation, as they say, directly 'on the ground,' that is, in the city Mariupol, as part of Russian and Ukrainian humanitarian convoys," Mizintsev said.

He also stated that Russia demands an official written response from Ukraine to all of its humanitarian proposals for ensuring the safety of Mariupol residents and the city's infrastructure by 05:00 local time on Monday.

it is worth mentioning that Russia has constantly opened humanitarian corridors allowing civilians to leave Mariupol and other Ukrainian cities in routes agreed upon with Ukraine.
