(AP) WASHINGTON - 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.

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.
