A Qatari ambassador for the World Cup, Khalid Salman, has called homosexuality a "damage in the mind" in an interview to be aired on German TV on Tuesday.
Salman, who previously played for Qatar's national team, told public broadcaster ZDF that the country will accept gay visitors during the upcoming World Cup but "they have to accept our rules".
He also insisted homosexuality was "haram" -- something forbidden in Islam -- during the interview, which was abruptly cut off after his comments.
Excerpts of the interview were shown on ZDF’s news program on Monday night. The full interview, which is part of a documentary, will be shown on Tuesday night.
Qatar has come under sustained fire over its human rights record ahead of the World Cup, including its treatment of foreign workers and its stance on women's and LGBTQ rights.
German Interior Minister Nancy Faeser on Tuesday criticised Salman's take on homosexuality.
"Of course such comments are awful and that is also the reason why we are working to hopefully improve things in Qatar in the future," said Faeser, who is also Germany's minister for sport.
Faeser said last week on a visit to Qatar that she will attend the World Cup after being given a "guarantee of safety" for LGBTQ fans by Qatar's prime minister.
The German minister on Tuesday said she had "no new indications from him that anything has changed".
Faeser described her trip to Qatar as "not easy" and said it had been "important for me to hold talks there to see who would do what for the safety of German fans during the World Cup".
German lawmakers joined Faeser on the visit, but the German government's human rights commissioner Luise Amtsberg pulled out.
Faeser had previously said Qatar's hosting of the World Cup was "very tricky" from Berlin's perspective, prompting Doha to summon the German ambassador.
Homosexuality is illegal in Qatar and captains from a number of leading European countries, including England, France and Germany, will wear armbands in rainbow colours with the message "One Love" in an anti-discrimination campaign.
Fans in stadiums across Germany on Saturday called for boycotts of the tournament.
