Iran has arrested two organisers of a marathon after women ran without wearing hijabs. The marathon took place on Kish Island, with 2,000 women and 3,000 men participating separately. Many women wore red t-shirts and did not cover their heads, breaking Iran’s strict dress rules. The images of unveiled women sparked mixed reactions. Supporters of change praised it as a sign of women rejecting Iran’s hijab laws. But officials called it "an unacceptable challenge" and said the race itself violated "public decency," according to Kish's prosecutor. The government's move reflects a wider conflict. Women’s participation in such public sports events, even separated by gender, was once not allowed. The debate over the hijab remains intense. Iranian authorities have fluctuated between easing and tightening dress code enforcement. The issue escalated after Mahsa Amini died in custody three years ago for allegedly breaking dress rules, triggering deadly protests. Since then, some women continue to defy hijab rules, prompting authorities to step up crackdowns. Gholamhossein Mohseni Ejei, head of the judiciary, ordered intelligence agencies to find "organised trends promoting immorality and non-veiling." This incident and the arrests show the ongoing struggle between Iranian leaders and many young citizens over women’s right to choose their clothing.
