The president of the Iranian Athletics Federation resigned on Sunday over the participation of women not wearing compulsory headscarves in a sporting event, state media reported.
"
Hashem Siami resigned from his post due to the controversies linked to an endurance race competition held in Shiraz
", a major city in southern Iran, the Irna agency reported.
According to images broadcast in the Iranian media, women participated in the test on Friday without wearing the Muslim veil.
This incident comes after the entry into force in mid-April of a new police plan to toughen the control of the wearing of the veil by women, compulsory since the Islamic Revolution of 1979.
The prosecutor of the province of Fars, where Shiraz is located, announced on Sunday that he would summon the organizers of the event to have "explanations
"
.
Mr Siami told Irna that his federation was not the organizer of the competition and that women not wearing the veil were not among the athletes of the federation.
In recent months, more and more women have appeared without veils in public places, especially after the beginning of the protest movement sparked by the death in custody in September of Mahsa Amini, arrested for breaching the strict dress code.
At least four famous actresses were harassed by authorities last week after appearing in public in Tehran without the compulsory veil.
On April 16, the authorities had indicated that more than 150 commercial establishments had been closed in 24 hours for not having respected the obligation of the wearing of the veil by employees.
In Shiraz, the police had arrested nearly a year ago several young girls who participated bareheaded in a skateboarding event, as well as the organizers.
