The Islamic supremacists are planning to increase the violence level in Saudi Arabia, with the goal of bringing down the ruling oil ticks: Saudi ‘Qaeda’ Leader Calls for Guerrilla Warfare. And these half-smart barbarians are beginning to realize that boasting openly about their exploits may not be the smartest thing to do.

DUBAI (Reuters) - A top al Qaeda leader in Saudi Arabia issued a battle plan on Thursday for an urban guerrilla war in the kingdom, already reeling from a recent spate of militant attacks on Western and security targets.

The Arabic-language statement, posted on several Islamist Web sites and purportedly from Abdulaziz al-Muqrin, gave a detailed list of steps militants should take to succeed in their violent campaign against the Saudi royal family.

“Working in cities needs small groups comprising no more than four people,” the statement said. “The activists must be residents of this city to avoid spies and suspicious eyes.”

It was not immediately possible to verify the authenticity of the statement but Islamist sites have in the past carried similar messages from Muqrin, said to have taken over the leadership of al Qaeda in Saudi Arabia after the killing earlier this year of top operative Khaled Ali Ali Haj. …

In the statement, Muqrin also urged his followers to “learn from the lessons of their predecessors” and inform potential attackers only about the role they will play and not about the whole plot.

“Most groups waging jihad have made the mistake of telling everyone everything about our operations,” he said.

“Only the group leader should know what is going on but everyone else should only be told about their role…for example, those who will conduct explosions should only be told about the explosion.”

In statements published on Islamist sites recently, Muqrin claimed responsibility for a shooting this month at an petrochemical complex in the Saudi city of Yanbu which killed five Westerners.
