South Korea Rescuers Use Explosives to Reach Workers Trapped at Collapsed Building

Imagine a giant metal building suddenly falling down.

In South Korea, some people were inside this building when it collapsed while they were trying to carefully take it apart.

Rescuers are trying hard to get to the ones still inside.

To help them reach the trapped workers, the rescuers used controlled explosions to knock down other tall parts of the building.

They hope this will make it easier and safer to find everyone, though sadly, some people are believed to be gone.
