Iran's supreme leader on Wednesday publicly endorsed for the first time the July nuclear agreement between Iran and six world powers, state news agencies reported .
The endorsement by the supreme leader, Ayatollah Ali Khamenei , is the final step in an approval process involving the Supreme National Security Council, the Iranian Parliament and the Guardian Council.
The endorsement was included in a letter addressed to President Hassan Rouhani that included accusations against the United States, Iran's longtime enemy, and that pointed out several ambiguities in the deal, state television reported.
Ayatollah Khamenei appeared to be trying to make clear on Wednesday that despite the landmark agreement, Iran would continue to view the United States as the "Great Satan," possibly to appease hard-liners, some of whom wept openly after Parliament voted to endorse the deal.
