U.S. Had Three-Day Warning of Attack, Claim Libyan Officials

If true, that would raise awkward questions

American diplomats were warned of possible violent unrest in Benghazi three days before the killings of US Ambassador Christopher Stevens and three members of his team, Libyan security officials say.

The claim came as the country's interim President, Mohammed el-Megarif, said his government had information that the attack on the US consulate had been planned by an Islamist group with links to al-Qa'ida and with foreigners taking part.
