After one of the biggest security swoops in years, the authorities in Saudi Arabia say scores of suspected militants with links to al-Qaeda have been arrested.
According to the interior ministry about 58 Saudis and around 50 Yemenis, in three independent groups, were planning to target oil facilities and security forces.
Others, it is alleged were said to have been establishing terrorist cells in the kingdom.
Interior Ministry spokesman, Mansour Al Turki said: “ We have uncovered a cell made up of a network of people specialising in targeting security men. In fact we know of instances where security men were put under surveillance by this network.”
Weapons, cameras documents and computers were said to have been seized with the suspects.
The operation shows that the Saudi oil sector remains a priority target for al-Qaeda which has been exploiting the instability on the Arabian peninsular.
