A Northern Ireland supporter suffered a suspected heart attack and died while watching his country beat Ukraine at Euro 2016 on Thursday, police said.

The man, in his sixties, collapsed in the upper section of the Stade de Lyon and paramedics were unable to revive him.

Fellow supporters left flags, shirts and scarves at the stadium in tribute to the dead man.

"The fan passed away as he was watching the game in the stadium. This puts any result of a football match into perspective," said Patrick Nelson, chief executive of the Irish FA.

"The thoughts of the board, management, players and staff are with his family and friends at this sad time."

He is the second Northern Ireland fan to die during the championships.
