Iran nuclear talks: Hope as John Kerry arrives in Geneva

The US Secretary of State John Kerry has arrived in Geneva amid hopes that a deal can finally be reached on Iran's nuclear programme.

He will be joined by the Foreign Secretary William Hague as negotiations enter their fourth day.

The West wants Iran to curb its nuclear activities, in return for an easing of sanctions.

The BBC's James Reynolds, in Geneva, said it could be seen as a good sign that foreign ministers were arriving but it was no means a done deal.
