French President Emmanuel Macron on Tuesday vowed to rebuild Notre Dame Cathedral, devastated by fire on Monday evening, within five years, calling on the French to remain united. In early Monday evening, a fire broke out in the famed cathedral. Online footage showed thick smoke billowing from the top of the cathedral and huge flames between its two bell towers engulfing the spire and the entire roof which both collapsed later.
