The death toll from a building collapse in South Africa climbed to 20, municipal authorities said Sunday, with 32 people still unaccounted for nearly a week after the structure came crashing down.

Rescue teams have been working tirelessly since an apartment block under construction in the southern city of George crumbled Monday afternoon while a crew of 81 were on site.
