We cleared many of their towns and cities and rural areas of al-Qaida Iraq and other insurgents.

Even the Interior Ministry in Riyadh was hit. Since then, the Saudis have employed a very intelligent and comprehensive approach to counter al-Qaida, including precise operations based on good intelligence, changes in their corrections facilities, superb strategic communications programs and a host of other initiatives - all of which, together, have helped Saudi Arabia achieve impressive results in their fight against extremists.
