South Korea Power Plant Collapse: 3 Dead, 2 Feared Dead, 2 Missing

Imagine a really tall, old chimney at a power plant that was being taken down.

While workers were cutting metal supports to help it fall safely, something went wrong.

The chimney collapsed, trapping several workers inside.

Sadly, three workers died, and two others are feared to have also died in the rubble.

Two more workers are still missing, and rescuers are trying hard to find them.

The chimney was built a long time ago and wasn't being used anymore.

Officials are now trying to figure out exactly why it fell down and if the safety rules were followed.
