APNewsBreak: Wikileaks says site is under attack (AP)

LONDON – The Wikileaks website, which contains thousands of U.S. embassy cables, has crashed in an apparent cyberattack.

The anti-secrecy organization said in a Twitter message Tuesday that Wikileaks.org "is presently under attack."

Efforts to view the Wikileaks site and view links to cables were unsuccessful.

The apparent cyberattack comes as the accelerated public disclosure of tens of thousands of previously unreleased State Department cables by the WikiLeaks organization has raised new concerns about the exposure of confidential U.S. embassy sources. That has created a fresh source of diplomatic setbacks and embarrassment for the Obama administration, current and former American officials said Tuesday.
