Iran nuclear talks under way in IstanbulMajor world powers have begun two days of talks with Iran over its controversial nuclear programme.
Diplomats meeting in Turkey are expected to revive a fuel-swap plan, where Iran gives up nuclear material in return for fuel for a research reactor.
US diplomats warned that major breakthroughs were unlikely.
The West suspects Iran aims to build nuclear weapons, and has imposed economic sanctions. Tehran insists its nuclear programme is peaceful.
