Al Qaeda promises more oil attacks coming

Al Qaeda in Saudi Arabia has promised more attacks after an attempted assault on the world's largest oil processing plant ended in a huge explosion at the site's gates.

On a website al Qaeda named two suicide attackers who died in the blast as Mohammed al-Ghaith and Abdullah al-Tweijri - both on a list of top wanted militants.

"We shall not cease our attacks until our territories are liberated," it said.
