VIDEO: Crane collapses during construction of apartment building



KIROV, Russia (FOX) -- A massive crane tips over and crashes into a nine-story apartment building in Kirov, Russia. Remarkably, nobody was hurt in this construction accident.

When it fell, the crane tore balconies off a building with more than 200 tenants.

Why the crane collapsed remains unknown.

Russia is in the midst of a building boom -- and critics say many builders are ignoring safety regulations.
