The newly declassified intelligence was made public May 22 by Frances Townsend, President George W. Bush's adviser for homeland security.
"The intelligence community tells us that in January of [2005] bin Laden tasked [al-]Zarqawi, who has been in Iraq, to form a cell to conduct attacks outside Iraq, and then frankly America should be his number one priority," she told reporters.
"We know from the intelligence community that Zarqawi welcomed the tasking and claimed he had already had some good proposals," she said.
Townsend declined, however, to specify any potential targets and would not say whether the plotters had advanced beyond the discussion stage.
Al-Zarqawi was killed in a U.S. air strike in June 2006.
