The official Emirates News Agency said that Ahmed bin Zayed Al Nahyan's glider went down in a lake in Morocco on Friday. The pilot of the aircraft was rescued in good condition, but authorities continued the search for Al Nahyan.

Al Nahyan is the managing director of the Abu Dhabi Investment Authority. He is also the younger brother of Sheik Khalifa bin Zayed Al Nahyan, the leader of the United Arab Emirates.
