The Stockholm International Peace Research Institute (SIPRI), a leading Swedish think-tank, has recommended US Secretary of State John Kerry and Iranian Foreign Minister Mohammad Javad Zarif for the 2016 Nobel Peace Prize for their leading roles in the nuclear deal, reports the International Business Times on Wednesday.

Tariq Rauf, director of SIPRI's Disarmament and Non-Proliferation Program and formerly chief of Verification and Security Policy at the UN International Atomic Energy Agency (IAEA) from 2002 to 2011, said the two deserved a Nobel prize.

He called the Iran nuclear deal the "single-most important multilateral agreement in decades," comparing it to the 1996 Comprehensive Test-Ban Treaty (CTBT) on nuclear detonation testing.
