The French Rugby Federation has warned Irish fans thinking of travelling to Paris for Six Nations games to expect heavy security.
After November's terrorist attacks there will be strict security checks around the Stade de France.
Spectators are advised to arrive to all games earlier than usual and no access will be given to latecomers.
People are also advised not to bring backpacks, sports bags or other bulky items to the grounds.
Ireland play France in their second match of the Six Nations tournament, at the Stade de France on Saturday February 13.
