Saudi Arabia's aging ruler had successful back surgery on Monday at the King Abdel Aziz medical compound in Riyadh, the official Saudi Press Agency said.
SPA quoted a Royal Palace statement as saying the 86-year-old King Abdullah's surgery was to treat a loose vertebra in his back and that the surgery was "completed with success, thank God."
The king arrived at the hospital Sunday night. A picture distributed by SPA showed him using a walking stick, but otherwise appearing healthy.
Abdullah had two back surgeries late last year in New York City.
