U.K. citizens are being urged to leave Benghazi, Libya today after Britain’s Foreign Office reportedly became aware of a “specific and imminent threat” to Westerners.

No details on the nature of the threat are available at this time.

More from the travel advisory:

We advise against all but essential travel to Zuwara, Az Zawiya, Tripoli, al Khums, Zlitan and Misrata, and the coastal towns from Ras Lanuf to the Egyptian Border, with the exception of Benghazi; we advise against all travel to all other areas of Libya, including Benghazi.

Hillary Clinton could not be reached for comment about “what difference” the threat makes.

Twitchy will monitor this developing story and update as more details become available.
