Ailing Saudi king, 91, admitted to hospital for checks

Riyadh: Saudi Arabia`s ailing King Abdullah, 91, was admitted to hospital on Wednesday for "medical checks," the royal court said.

The king, whose age and frequent hospitalisation have raised concerns about the future leadership of the key oil producer, was admitted to the King Abdulaziz Medical City in Riyadh, a court statement carried by the official SPA news agency said.

Abdullah`s half brother Salman, 77, is next in line to the throne.
