Iranian officials have arrested six people accused of teaching Zumba dancing and trying to "change lifestyles", media reports say.

The group of four men and two women were charged over their dancing and not adhering to the hijab dress code.

Instructors allegedly "attracted boys and girls, taught them Western dances", and posted videos to social media.

The Latin American fitness routine has proved controversial in Iran, which has laws restricting dance.

"The members of a network teaching and filming Western dances have been identified and arrested," Hamid Damghani, a commander of Iran's Islamic Revolutionary Guard Corps, was quoted as saying by local media outlets.

The case has some parallels to the 2014 arrest of six Iranians for dancing along to Pharrell William's song Happy - which saw them sentenced to 91 lashes and a prison term.
