The Iranian judiciary says two organisers of a marathon have been arrested for allowing women who were not wearing hijabs to take part, BBC reported.

The move comes after images appeared online of unveiled women competing in the race on Friday.

Two thousand women and 3,000 men took part separately in the marathon on Kish Island off the southern coast of Iran.

Dressed in red t-shirts, some of the women competitors were clearly not wearing the hijab or any other head covering, according to BBC.
