Iran's hard-liners are criticizing a tentative nuclear agreement between Iran and world powers, saying the deal was a bargain for the West and a disaster for Iran.

Hossein Shariatmadari, an advisor to Iran's Supreme Leader Ayatollah Ali Khamenei and editor of the hard-line Kayhan daily told the semi-official Fars news agency on Friday that Iran exchanged its "ready-to-race horse with a broken bridle."

Another conservative analyst, Mahdi Mohammad, referred to the Fordo underground uranium enrichment facility and told the news outlet that under the deal, "A disaster happened in Fordo."

Iran agreed to stop enrichment at Fordo, changing the facility to a nuclear research center. The proposed deal limits Iran's nuclear program in return for an end to crippling economic sanctions.
