Sunday night's UEFA Nations League game between England and the Republic of Ireland was preceded by booing during both national anthems.
Jeering began in the away section when a large group representing the UK military were paraded on the field ahead of the match.
England fans responded by later booing Amhran na bhFiann. In return, Irish supporters booed God Save the King.
The lack of respect shown to both anthems was the topic of plenty of discussion on social media.
One comment on X (formerly Twitter) read: 'England fans booing a national anthem is such a scummy thing'.
Another read: 'Irish fans singing the national anthem louder than the English fans were booing.'
Meanwhile, English journalist Henry Winter tweeted: 'Jeer we go. Both anthems getting booed. Both associations getting fined.'
Irish journalist Daniel McDonnell added: 'Spirited booing of both anthems, with the Irish fans not too impressed by the poppy season military ensemble functioning as the backing dancers'.

While I was watching, I was booing the fans who were doing this.
