(Newser) – The White House has stepped up security efforts to prevent September 11 from becoming the anniversary of any more tragedies. The administration, citing last year's 9/11 attack in Benghazi, has ordered increased security at American facilities around the world today and has put top counterterror aide Lisa Monaco in charge of reviewing operations, reports Reuters. "The president's national security team is taking measures to prevent 9/11-related attacks and to ensure the protection of US persons and facilities abroad," the White House said in a statement.
