Times Of Israel 
Sept 30, 2012
The US Embassy in Cairo issued a terrorist threat warning on Friday for American citizens living in Egypt.
The diplomatic mission stated on its website that it has “credible information suggesting terrorist interest in targeting US female missionaries in Egypt.”
The embassy urged US citizens to “exercise vigilance, taking necessary precautions to maintain their personal security.” Americans in Egypt were also advised to maintain valid travel documents and to regularly monitor the US Department of State’s Bureau of Consular Affairs website, which lists updated travel warnings and alerts.
On August 4, the US issued a travel warning to Americans to “take precautions in travel to the Sinai.” It warned that “overland travel from Israel to the Sinai in particular is strongly discouraged.” That warning came soon after Israel urged its citizens to get out of the Sinai. The next day, Sinai terrorists killed 16 Egyptian border guards in an assault at the Egypt-Gaza-Israel border.
