About 100 suspected terrorists linked to al Qaeda have been arrested in Saudi Arabia.
The Saudi Interior Ministry said the group of 47 Saudis and 51 foreigners had been preparing to launch terror attacks on oil installations. Saudi Arabia is the world's biggest oil exporter.
Officials say bomb belts, other weapons, cameras, and computers were seized.
In 2003, Muslim terrorists tried to overthrow the Saudi monarchy, killing nearly 200 people.
