Nobody heard anything about the 2nd wife Natasha/Aisha so I don't know how we can claim that she is raising her children but then you never know what's really going in the minds of Sheikh Saeed.
If she wasn’t with her daughters we would probably hear about it,,
His first wife with all the problems she caused ( and yes they took her children from for what seems to be a good reason) is living in Dubai with no restrictions and does travel. She was last year in Saudi visiting friends.
It does not make sense to me why he suddenly wants to do all this unless she was trying to flee the country with their daughters??
