The United States, Britain and Australia have all posted warnings that terrorists could soon strike again in Saudi Arabia.
Americans in Saudi Arabia have been warned they could be the target of terrorist attacks during the upcoming Muslim holy month of Ramadan.
The U.S. Embassy in Riyadh placed the warning on its telephone system Saturday.
"The Embassy continues to receive information that terrorist groups within the kingdom are still active and planning future operations. It is the Embassy's assessment that terrorist groups may place special operational significance on the upcoming month of Ramadan, and American citizens are therefore urged to be particularly vigilant during this time," stated the embassy recording.
Britain and Australia have posted similar warnings. The British advisory says British citizens should defer all but essential travel to the kingdom.
Both Britain and Australia say terrorists in Saudi Arabia could be in the final stages of planning attacks.
A series of bombings on Western residential compounds in Riyadh in May killed 35 people. Saudi Arabia says it has arrested nearly 600 suspected militants since those attacks.
