Reports from Saudi Arabia say about 100 suspected militants linked to al-Qaeda have been arrested. The suspects were said to be planning attacks on oil installations in the world's biggest oil exporter. The suspects included Saudi nationals and foreigners, reports said. Weapons, cameras, documents and computers were also seized. There is no confirmation. In 2003, suicide bombers suspected of having links with al-Qaeda killed 35 people in the capital Riyadh. They included a number of foreigners.
