Iran's supreme leader Ayatollah Ali Khamenei has warned President Hassan Rouhani that "some" world powers are not to be trusted in implementing a nuclear deal, urging vigilance for any breaches.
In a letter to Rouhani, Khamenei, who had the final word on the historic deal struck Tuesday with six powers led by the United States, congratulated Iran's negotiators for "their tireless efforts".
Bringing the talks to a close was a "milestone", Khamenei said, but the agreement requires "careful scrutiny" before it is approved.
Rouhani "must be concerned about possible violation of commitments by the other parties and close paths to it," the leader wrote in the letter, published on his website late Wednesday.
"You are well aware that some of the six states participating in negotiations are not trustworthy at all," Khamenei said.
He did not specify which of the six countries -- Britain, China, France, Russia and the United States plus Germany -- he was referring to.
Throughout the almost two years of negotiations that culminated in the landmark agreement, Khamenei often spoke of his distrust of the United States.
