Terrorism: U.S. citizens in the United Arab Emirates should exercise a high level of security awareness, even though law enforcement units have effectively demonstrated the capacity to detect, deter, and prevent acts of terrorism in the UAE. The Department of State remains concerned about the global threat of terrorism, including the possibility of terrorist attacks against U.S. citizens and interests in the Gulf and Arabian Peninsula. Both historical and current information suggest that the Islamic State of Iraq and Syria (ISIS), al-Qaida, and affiliated organizations continue to plan attacks against Western targets; these attacks may employ a wide variety of tactics, including suicide operations, assassination, kidnapping, hijacking, and bombing. Rebel groups operating in Yemen have stated an intent to attack neighboring countries, including the UAE, using missiles and unmanned aerial systems (drones). These groups have already launched long-range missiles and unmanned aerial systems into Saudi Arabia, specifically targeting populated areas and civilian infrastructure; they have publicly stated their intent to continue doing so. U.S. citizens are strongly encouraged to maintain a high level of vigilance and take appropriate steps to increase their security awareness when traveling. U.S. citizens should maintain a low profile, vary routes and times for all required travel, and treat mail and packages from unfamiliar sources with caution. In addition, U.S. citizens should avoid contact with any suspicious, unfamiliar objects and report the presence of the objects to local authorities. U.S. government personnel overseas have been advised to take the same precautions. U.S. government facilities may temporarily close or suspend public services from time to time, as necessary, to review their security posture and ensure its adequacy
