Alarm grew on Tuesday over the wellbeing of Iranian sports climber Elnaz Rekabi after she competed at an event in South Korea without a hijab in what some saw as a gesture of solidarity with the women-led protests at home. Rekabi, 33, in her first comment since the event at the Asian Championships in Seoul on Sunday, apologised on Instagram for the "concerns" caused and insisted her bare-headed appearance had been "unintentional".
