The Obama administration has been heralding the deal brokered with Iran and other world powers to curb Tehran's nuclear program but Iran's top leader isn't ready to give it the thumbs up yet.
The Associated Press reports that the real leadership in Iran is holding off on approving the deal.
In what appears to be a bargaining tactic, Supreme Leader Ayatollah Ali Khamenei says in remarks published Thursday on his official website that he "is neither for nor against" the deal, which is to be finalized by June 30.
Khamenei, who has final say on all state matters, says there "is no binding" agreement yet.
The deal, much lauded by the Obama administration, has been denounced by Israel and criticized by Republicans.
In what can only be described as faint praise for the deal, the Harper government said all diplomatic efforts must be made to stop Iran from getting the bomb but then issued a stern warning not to trust Iran.
