An Internet posting purportedly by al-Qaida in Yemen says the group's second in command is a Saudi national released from Guantanamo in 2008.
The posting by the Yemeni group - known as "al-Qaida in Arabian Peninsula" - surfaced on jihadi Web sites that regularly carry al-Qaida messages.
It says the man returned to his home in Saudi Arabia after his release from Guantanamo and from there went to Yemen to join the terror group.
He was identified as Said Ali al-Shihri, said to be his real name, and also as Abu Suffyyan al-Azdi al-Shihri, a nom de guerre. It says his prisoner number in Guantanamo was 372.
The statement says al-Shihri attended a meeting of al-Qaida commanders in Yemen during which the top leader gave an interview to a local journalist.
