The Czech Foreign Minister has summoned UK ambassador Nick Archer after the Glen Kamara race row escalated into a diplomatic row.
Jakub Kulhanek took to social media to express his rage at what he described as “disgusting insults” against the young Sparta Prague fans who jeered Kamara throughout Rangers’ Europa League game.
The Fortuna liga club released a furious statement calling for a halt to criticism of the school kids who were allowed into the Letna Stadium.
Ibrox boss Steven Gerrard had hit out at the jeers in his post-match press conference after the game was supposed to be played behind closed doors as a result of previous racist abuse during a match with Monaco.
That was relaxed by UEFA to allow supervised Under-14s in the ground but they booed Kamara as well as other black Rangers players.
Their actions have been widely condemned but Kulhanek took to social media to say: “Enough! Intentionally spread, disgusting insults against Czech children in the media and on the internet do not belong to football and even less so to good relations between two countries.”
Sparta Prague said early as part of their statement: "Stop attacking our children! Our club will proudly defend our children - our future and our pride. Slandering children on the internet is extremely cowardly.
"We are seeing unprecedented xenophobic statements against the Czech Republic, its citizens and even its children on social media.
"You are describing the behaviour of children incorrectly, arrogating to yourself the right to judge the expression of emotions of six-year-old children who have no idea what racism is. It's an impertinence.
"We ask the representatives of Rangers FC to do their part to stop the xenophobic atmosphere directed towards our children, our beautiful country and its inhabitants."
