Tower demolition goes spectacularly wrong

The demolition of an old concrete silo tower in Denmark has gone horribly wrong - collapsing on a library building.

A video of the unsuccessful demolition in the Danish town of Vordingborg on Friday was posted on YouTube.

It shows the old 173-foot tower being blown up by experts and then crashing down on the library building.

It is understood no-one was injured during the demolition site.
