UK Foreign Secretary William Hague and US Secretary of State John Kerry have joined other foreign ministers in Geneva in the hope of finally reaching a deal on Iran's nuclear programme.

The latest round of negotiations are entering their fourth day after the talks were extended to find an agreement that would be acceptable to both sides.

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

Mr Hague said any agreement would have to be "thorough and detailed".
