The U.S. tightens security at diplomatic missions in Lebanon and Turkey on Friday - because of unspecified threats.

In Lebanon, the U.S. State Department ordered all non-emergency diplomatic personnel and their families out of the country -

and in southeastern Turkey - a voluntary evacuation at the consulate in Andana has been ordered.

U.S. citizens have been warned against traveling to these regions - and Americans in the rest of Turkey have been told to remain vigilant.

Officials offered no additional information about the threats - which come just a week before the anniversary of the September 11 attacks.

Despite the ramped up security - some U.S. citizens living in the Lebanese capital - Beirut - said they did not feel an urgency to leave.

(SOUNDBITE) (English) AMERICAN CITIZEN, ALEXANDRA TALTY, SAYING:

"I am not going to leave because of the U.S. embassy urging its citizens to leave, but if they were to evacuate, I would leave."
