(ECNS) -- Spire of Notre Dame Cathedral in Paris collapsed in a huge fire on Monday afternoon local time.
Online footage showed a thick smoke billowing from the top of the cathedral and huge flames between its two bell towers engulfing the spire and the entire roof, both of which collapsed.
It may be linked to renovation works being carried out at the medieval cathedral, one of the capital's tourist magnets.
Paris authorities have launched an investigation into the cause of the blaze.
