U.S. intelligence officials say that ahead of the one-year anniversary of Osama bin Laden's killing, there are no "credible" terror threats against the United States.
"While there is no credible threat, there is much preparation based on the common sense consideration of the date," an intelligence official told ABC News.
Officials also told ABC News that while there are several threats against the United States and its interests that are being investigated; they are currently deemed to be low credibility.
An advisory issued Wednesday by FBI and Homeland Security, however, warns of "renewed efforts to target Western aviation," according to an advisory obtained by ABC News.
Bin Laden was killed by U.S. Navy SEAL Team Six on May 2, 2011 during a late-night raid of the compound where the terror leader was living in Pakistan. Following the raid and the killing, there were renewed calls for attacks against the U.S. as retribution.
