Iranian authorities sentenced a member of Iran's nuclear negotiating team to five years in jail, Tasnim news agency reported on Wednesday although it gave no details of the case.

Iran reached a nuclear deal with the United States and five other major powers in 2015 that led to the lifting of most of the international sanctions against Iran in return for curbs on its nuclear program.

The potential detente with the West has alarmed Iranian hardliners, who have seen a flood of European trade and investment delegations arrive in Tehran to discuss possible deals, according to Iran experts.
