Moment part of Notre Dame spire collapses in Paris

The main spire at the top of Notre Dame Cathedral collapsed in a devastating fire at Paris Cathedral today (April 15).

The filmer wrote on Twitter: "The fall of the great spire of Notre-Dame in front of the Eiffel Tower and the powerless Parisians..."

Firefighters are fighting to save the 850-year-old Gothic building, but its spire and roof have collapsed.

The main structure has now been "saved and preserved" according to a Paris fire official.

The cause is not yet clear, but officials say it could be linked to renovation work.
