Saudi Crown Prince Nayef bin Abdul Aziz, the kingdom's veteran internal security czar, arrived in the U.S. city of Cleveland on Friday for scheduled medical tests, the royal palace announced in Riyadh."The crown prince, (who is also) deputy prime minister and interior minister, arrived in Cleveland from Morocco for medical examinations that had been previously scheduled," the palace said in a brief statement carried by the official SPA news agency.
It did not elaborate on what the tests were for.
Prince Nayef -- who has served as interior minister for nearly four decades and led the kingdom's post-September 11, 2001 crackdown on al-Qaeda -- was named crown prince in October last year at the age of 78, following the death of his brother, Prince Sultan.
