A recent and explicit threat from al-Qaeda has made the U.S. take many preemptive measures to protect its citizens at home and abroad.
All major airports, railway stations, and other transportation methods have received additional security as a result of the threat, which came from the Arabian Peninsula. Diplomatic posts in 19 cities in the Middle East will remain closed until August 10th.
Officials say that an attack on the U.S. was not mentioned in the intercepted transmission between two al-Qaeda operatives, but the Department of Homeland Security and the Federal Bureau of Investigation has sent out warning bulletins across the country just to be safe.
The U.S. travel site also issued a travel warning for all citizens of the country, most specifically for those who are in or will be traveling to Yemen. It is anticipated that the attack may be focused there, but there is no concrete evidence either way. There is a large amount of mystery surrounding the target of the planned attack, which is said to be in its final stages, so officials are increasing security standards across the board as a precaution to ensure homeland security in the U.S.
