The United States Secretary of State Hillary Clinton has accepted all 29 recommendations in a report into September's deadly attack on the US consulate in Benghazi, Libya.
The report found that systemic failures at the State Department led to inadequate security at the consulate.
But it found no individual official ignored their duties, and the review has not suggested disciplinary action, the BBC reports.
Ambassador Christopher Stevens and three other Americans were killed in the attack on 11 September.
At the time, Washington said the assault arose from a spontaneous protest but later intelligence pointed to terrorism.
