Rival Argentina and Mexico fans came to blows in Qatar on Wednesday night after chants of "f*** Messi" were heard.
Video footage of the incident captured a brief fight between the rival sets of fans, clad in their nation's kits, at the Al Bidda Park in Doha - one of FIFA's fan zones in the Qatari capital, which is designed to encourage different teams coming together to mingle.
The ugly scenes came just a day after Argentina suffered a shock World Cup defeat by Saudi Arabia to open their campaign, despite being among the favourites for the competition. Messi opened the scoring for the South American nation from the penalty spot after a highly contentious spot-kick decision but his side were stunned by two second-half goals.
