Hard-line Iranian politicians are publicly criticizing the historic deal reached in Geneva last week over the Islamic Republic's nuclear program.

Hard-line lawmaker Ruhollah Hosseinian said the deal was so vague and conditional that it may finally lead to a shutting down of Iran's uranium enrichment program. Hamid Resaei, another hard-line lawmaker, has called deal "a poison chalice."

Most lawmakers supported the deal, saying it eases international sanctions that world powers have placed on Iran and prevents them from imposing new ones.

Discussions over the deal were broadcast live on state radio as Foreign Minister Mohammad Javad Zarif briefed lawmakers on the historic deal.

The U.S. and its allies fear that Iran may be able to develop a nuclear weapon, a charge Tehran denies.
