From the Independent (prominently featured on Drudge):
According to senior diplomatic sources, the US State Department had credible information 48 hours before mobs charged the consulate in Benghazi, and the embassy in Cairo, that American missions may be targeted, but no warnings were given for diplomats to go on high alert and “lockdown”, under which movement is severely restricted.
The Obama administration is flatly denying a blaring British newspaper report that the U.S. diplomats in Libya were killed as a result of a “continuing security breach,” and that “credible information” about possible attacks had been ignored.
