“We are in contact with his next of kin and we are still seeking from the Saudi authorities reasons for his detention,

In the message on the site the group also claimed to have shot dead a general in the Saudi security forces on Friday.
In a statement signed the “Brigade of Death for Special Operations,” the group threatened to “cleanse Saudi Arabia, the country of the two holy mosques, of anyone who has helped the United States in one way or another against the mujahidin (holy warriors), and those involved in their torture in Saudi prisons in Hayer, al-Roweiss, Allicha and others.”
The statement goes on to say that “Since our brothers in the al-Qaida organisation are busy with the war against the
crusaders, we have decided to take care of cleansing the country of crusaders.”
Saudi security forces have been on heightened alert since the 12 May and 8 November attacks on residential compounds in
Riyadh which killed a total of 52 people.
They have been hunting suspected armed dissidents for several months, resulting in hundreds of arrests as well as gunbattles between suspects and security forces.
