In the catacombs of a steel plant in Mariupol, Ukrainian soldiers stage a last stand against Russian occupation as their wives plead with aid groups to evacuate them along with civilians.

The final battle for Mariupol is taking place inside the Azovstal steel plant, a massive coastal complex in the besieged city. Hundreds of civilians are still trapped inside, officials say.
