Al-Qaeda in Yemen demands the release of its members detained in Saudi Arabia in exchange for the release of a Saudi diplomat captured in Yemen, according to media reports. The fate of Abdullah Al-Khalidi remained uncertain on Tuesday. He was kidnapped in the port city of Aden three weeks ago. Security Chief of Aden, Sadeq Haid, has said Al-Khalidi will be freed soon. But other sources said that Al-Qaeda militants captured the Saudi diplomat. Earlier reports said the diplomat was kidnapped by supporters of the former president Ali Abdullah Saleh to distort the image of the interim government.
