For women and children stuck in the bunker of the Azovstal steelworks, daylight is a rarity.
"I want to get out of here and see the sun. We’ve been here for two months now and I want to see the sun," said one boy.
As the barrage of Mariupol continues, the plant is among the last significant holdouts of Ukrainian forces in the city and is sheltering hundreds of soldiers and civilians.
"Because they switch the lights on and off here. When they rebuild our houses we can live in peace. Let Ukraine win this war because Ukraine is our dear home," he added.
Some background: Ukrainian officials have said more than 100,000 people still remain in Mariupol. The Russian government claims to control the strategic port, but Ukrainian fighters remain holding out in the city's massive Azovstal steelworks.
On Friday, Russian troops also continued to launch air strikes on Mariupol and restrict Ukrainian units in the area of the Azovstal plant.
The situation at the Azovstal steel plant in Mariupol is “close to a catastrophe," Yuriy Ryzhenkov, the CEO of the company that owns the plant, told CNN on Thursday.
“When the war started we had stocked quite a good stocks of food and water in the bomb shelters and the facilities at the plant so for some period of time the civilians, they were able to use it and basically survive on that. Unfortunately all the things, they tend to run out, especially the food and daily necessities. I think now it’s close to a catastrophe there,” Ryzhenkov, who runs Metinvest Holding, told CNN's Julia Chatterly on the "First Move" podcast.
Ryzhenkov said originally there had been enough supplies for two to three weeks but they were almost eight weeks into the blockade. He added that those still there “were not giving up.”
Evacuation corridor "thwarted": The evacuation of civilians from the besieged Ukrainian city of Mariupol has been "thwarted" by the Russian military, an adviser to the mayor of Mariupol said on his official Telegram account Saturday.
At 11 a.m. local time (4 a.m. ET) Saturday, at least 200 residents had gathered near a shopping center in Mariupol, waiting to be evacuated to Zaporizhzhia. But "instead of the buses promised by the Russian side, the Russian military approached the Mariupol residents and ordered them to leave because 'there will be shelling now,'" Petro Andriushchenko said.
