RIYADH, Saudi Arabia (AP) — A top Saudi security official said Tuesday that police had arrested 88 men suspected of being part of an al-Qaida cell that was plotting attacks inside and outside of the kingdom. Interior Ministry spokesman Mansour al-Turki did not give any details about the alleged plots, but said 59 of men arrested had previously served prison sentences for similar offenses. Saudi security officials began battling al-Qaida militants around a decade ago when extremists launched a string of attacks in the kingdom aimed at toppling the monarchy.
