Al-Qaida militants in Yemen have posted online a second video of a kidnapped Saudi Arabian diplomat appealing to his kingdom's rulers to grant his captors' demands and save his life.

The three minute clip that appeared on a militant Web site early Monday was similar to another video released in May: The speaker identified himself as Abdullah Mohammed Khalifa al-Khaldi , deputy Saudi consul in the Yemeni port city of Aden, who was kidnapped in March. There was no sign of his captors in either video.

He asks Saudi Arabia's King Abdullah and his government why they do not release female militant detainees as his abductors have demanded.

The Saudi Interior Ministry has said earlier that the demands also include paying a ransom and releasing other male prisoners.
