The United Nations human rights office has asked the United Arab Emirates for proof that Princess Latifa, the daughter of Dubai’s ruler, is alive.
The watchdog also requested the UAE provide more information about her status, a spokesperson said.
In videos, Princess Latifa accused her father of holding her hostage in Dubai since she tried to flee in 2018.
In secretly recorded videos shared with the BBC, Princess Latifa said she feared for her life.
The footage, released by friends, prompted global calls for a UN investigation, while the UK said it would watch any developments “very closely”.
“We are concerned about it,” UK Foreign Secretary Dominic Raab said earlier this week, adding that the “deeply troubling” videos showed “a young woman in deep distress”.
Princess Latifa’s father, Sheikh Mohammed bin Rashid Al Maktoum, is one of the richest heads of state in the world, the ruler of Dubai and vice-president of the UAE.
The UAE has close relations with a number of Western countries, including the US and UK, which consider it a strategic ally.
