An official source at the foreign ministry said Wednesday Bandar expressed his wish to be relieved from his responsibilities earlier this month.
"After all these long years of devoted service as Saudi Arabia's ambassador to the United States, which exceeded 20 years, Prince Bandar solicited King Fahd to be released from his post for personal reasons," the source said.
He said the king appointed Prince Turki al-Faisal, the current ambassador to Britain, to replace Bandar.
The source did not say what prompted Bandar to resign.
