A Northern Ireland fan has died at the Stade de Lyon after collapsing during their Euro 2016 match with Ukraine on Thursday.
The man, in his sixties, collapsed in the upper part of the ground and was treated by paramedics but they were unable to revive him.
Northern Ireland won the match 2-0, but Irish FA boss Patrick Nelson said: "This puts any result of a football match into perspective. The thoughts of the board, management, players and staff are with his family and friends at this sad time."
