Ukrainian President Volodymyr Zelensky said during an address Sunday that for the first time today, the vital corridor to evacuate civilians from the Azovstal steel plant in Mariupol had started working.

Zelensky said for the first time, there have been two days of “real ceasefire” and added more than 100 civilians have been evacuated from the plant.

Earlier on Sunday, Ukrainian authorities alongside the UN and the International Committee of the Red Cross confirmed that an effort to evacuate civilians sheltering in the plant was underway.

The plant has been subject to heavy Russian bombardment in recent weeks. Hundreds of people, dozens of whom are injured, are thought to be inside the steel-making complex.

Zelensky said the first evacuees will arrive in Zaporizhzhia on Monday morning where the Ukrainian government will meet them. He added the Ukrainian government will continue to evacuate people from Mariupol on Monday, starting approximately around 8 am local time.

The evacuation of civilians from the besieged Ukrainian city of Mariupol has been paused from Sunday night until Monday due to “security reasons,” the Mariupol City Council said in a Telegram post.

Evacuations will now commence at 8 am local time (1 am ET), near the Port City shopping center in Mariupol, the post added.
