After a moment of silence Tuesday to honor victims of the terror attacks in France, the French Parliament's National Assembly spontaneously sang "La Marseillaise," the country's national anthem.
In the video above, one male voice in the chamber can be heard singing before others join in. It was the first time the National Assembly had sung "La Marseillaise" together since 1918, Slate noted.
According to Yahoo, lawmakers began the tribute by naming all 17 victims of last week's attacks.
The anthem has also been played outside the country as a show of solidarity. The Montreal Canadiens of the National Hockey League played "La Marseillaise" before its game on Saturday.
