The White House said, Thursday evening, that President Barack Obama of the United States undertook a review of potential threats on the anniversary of the elimination of Al-Qaeda terrorist leader Osama Bin-Laden but there was no solid evidence that Al-Qaeda was planning any revenge activity.

In a prepared statement, Spokesman Jay Carney said, "At this time, we have no credible information that terrorist organizations, including al-Qaeda, are plotting attacks in the U.S. to coincide with the anniversary of bin Laden's death."
