The White House is dismissing as "baseless" a controversial report alleging President Barack Obama's administration lied about the circumstances surrounding the 2011 killing of Osama bin Laden, CNN reports.

"There are too many inaccuracies and baseless assertions in this piece to fact check each one," White House National Security spokesman Ned Price said in a statement to reporters.

He took aim specifically at journalist Seymour Hersh's assertion that the administration collaborated with Pakistani officials to kill the Al Qaeda leader, saying that "the notion that the operation that killed Osama Bin Laden was anything but a unilateral US mission is patently false."

"As we said at the time, knowledge of this operation was confined to a very small circle of senior US officials. The president decided early on not to inform any other government, including the Pakistani government, which was not notified until after the raid had occurred," Price said.

"We had been and continue to be partners with Pakistan in our joint effort to destroy the Al Qaeda, but this was a US operation through and through."

It was the White House's first response to Hersh's stunning report, published this weekend in the London Review of Books, outlining what he describes as the true circumstances surrounding Laden's death.
