A call made by a local sports federation to ban Zumba dance classes across Iran has angered many online.
The Iran Sport for All Federation penned a letter to Iran's Ministry of Youth Affairs and Sports to ban activities, including Zumba, for contravening "Islamic ideology".
The federation has the country's highest membership status in the Association for International Sport for All (Tafisa) that is based in Frankfurt. Founded in 1992, the Iran Sport For All Federation is a licensed regulatory authority for a range of sports and operates provincial branches and offices in state organisations.
A Tafisa official told the BBC that the association does not have a say in political decisions made by the Iran federation. It added that decisions on Tafisa membership are taken by its board of directors.
Many Iranian social media users criticised the proposed ban, using the Persian-language hashtag #Zumba.
Iran Sport for All President Ali Majdara's letter, posted on the Iran's sports ministry website on 7 June, said the aim was to "develop athletics for everyone in the framework of supreme Islamic ideology and the Islamic Republic of Iran's sport structure".
"Please issue a regulation to ban some activities, such as Zumba, which include rhythmic motions and dance and are unlawful in any shape and title," the letter continued.
One Twitter user joked: "The Oscar for the most Daeshi [so-called Islamic State group] news of the day goes to this..."
"Have Colombia not summoned the Iranian ambassador yet?" another added - the Latin dance is said to have originated in Colombia.

"How many pillars does Islam have? One is at risk for the non-observance of hijab, another one over women watching sport matches in stadiums, the third for holding music concerts, the next for epilation and, the most recent one, for Zumba," one Twitter user commented.
