The French rugby league federation will donate the proceeds from its upcoming test match against Wales to victims of the Aude floods.
At least 13 people were killed by the flash floods in the southwest of France earlier this month in the worst flooding in the area for more than 100 years.
France will take on Wales in Carcassonne, prefecture of Aude, in the European Championship on October 27 and all match ticket sales will be donated to support flood victims.
Nigel Wood, President of the Rugby League International Federation, said: “In response to the tragic events in Aude in France, where floods have left more people dead and many wounded and missing, the International Rugby league (RLIF) sent a message of support to the French Federation rugby league (FFRXIII) and the large number of members of the family of rugby league who have been affected in the region.
“It is sad to see the images of this disaster unfold in such familiar places for rugby league players in the world. It’s very hard when we see someone in distress, when these people are part of our global family, we must help where we can.”
The Stadium Albert Domec in Carcassonne will also see France Women take on England as a curtain raiser to the men’s game.
France, beaten 44-6 by England at Leigh Sports Village last week, also travel to Ireland on November 3 and host Scotland, also in Carcassonne, on November 10.
All games in the European Championship will be streamed live online via the BBC Sport website.
