Saudi Arabia's veteran foreign minister Prince Saud al-Faisal has undergone neck surgery in New York, the official news agency said late on Saturday. The report from the Saudi Press Agency said the senior member of the ruling Al Saud family, who has been foreign minister since 1975, was treated successfully on Friday to remove bone calcification. It said the prince would return to Saudi Arabia after a convalescence period. He could head the Saudi delegation to a Middle East peace conference including Israel later this year, if the leading Arab-Muslim power agrees to attend. The Saudi Foreign Ministry says Prince Saud was born in 1940 making him one of the younger figures among the key players in the royal family.
