Iran nuclear talks: UK warns sides 'far apart' on deal
Iran and foreign ministers from six world powers are still "a long way apart" on agreeing a nuclear deal before Monday's deadline, the UK's foreign secretary has warned.
Philip Hammond was speaking after another day of talks in Vienna, Austria.
The six nations - US, UK, Russia, China, Germany and France - want Iran to curb its nuclear programme in return for the lifting of UN sanctions.
Iran says it is not seeking nuclear weapons, but wants atomic energy.
