The wife of Dubai's ruler, Sheikh Mohammed bin Rashid al-Maktoum, has applied to a British court for what's called a "forced marriage protection order." It's a British legal measure designed to protect someone who says they were forced into marriage from harassment or threats.
Princess Haya bint al-Hussein, the half-sister of Jordan's King Abdullah, also asked for wardship of her children and a non-molestation order.
No other details are known and it's not clear whom the marriage protection pertains to.
The UAE embassy declined comment and while she attended court, he did not.
The BBC reports that the children left Dubai with her and the Sheikh has applied for their return.
If Princess Haya ran away from the sheikh's court, she appears not to be the first to do so.
One of Sheikh Mohammed's daughters by a different wife is believed to be being held incommunicado in an undisclosed location in the UAE.
Sheikha Latifa tried to flee Dubai on a boat that was then intercepted.
She was forcibly returned to the emirate.
Seventy-year-old Sheikh Mohammed has more than 20 children by different wives.
Princess Haya is believed to be his sixth wife.
