Iran left a message saying "may peace, respect and friendship prevail among all nations" following their World Cup group match against Belgium at Los Angeles Stadium.

The handwritten note was left in their dressing room following a goalless draw in their second Group G game.

Iran are competing at the World Cup while their country and the United States - who are co-hosts along with Canada and Mexico - are in negotiations to end their war.

"From the ancient Persia of thousands of years ago to the civilised Iran of today, the spirit of Iran remains alive and steadfast," read the message, which was released by the Football Federation of Iran (FFIRI).

"We came to Los Angeles with pride, competed with honour, and leave with dignity," the note continued.

"Thank you Los Angeles for your hospitality.

"And thanks you to every Iranian who gave their heart, voice and soul for Iran throughout these 180 minutes.

"May peace, respect and friendship prevail among all nations."

The message also made reference to an attack on a girls' school in Minab, where at least 168 people were killed on the first day of the war.
