7 US Embassies included Armenian are warned over the possibility of attack

U.S. embassies in at least seven countries in the Middle East, Africa and the Caucasus are warning of possible anti-American protests following the attack on the consulate in Benghazi, Libya that killed the U.S. ambassador to Libya and three other Americans. Huffington Post writes about this.
The embassies in Armenia, Burundi, Kuwait, Sudan, Tunisia and Zambia, along with the embassy in Egypt, which was hit by a protest on Tuesday, all issued warnings on Wednesday advising Americans to be particularly vigilant.
The warnings, posted on the embassies' websites, do not report any specific threat to Americans but note that demonstrations can become violent.
The protest in Cairo and the attack in Benghazi appear to have been responses to an inflammatory anti-Muslim video posted on the Internet.
Note that this article in the Huffington Post magazine has 181 comments. One of the commentators asks to explain to him why US embassy in Armenia is warned? ''There are fewer than 1,000 Muslims in Armenia. Armenia is the first Christian nation and has no association to Islam, nor has any ill will towards America. There's more ill-will towards Muslims, like Turks, than anybody else in Armenia'', the user says.
