Nuclear talks: Iran says 'no new ideas' on table
Iran's foreign minister has said he heard "no new ideas" as talks on Tehran's nuclear programme stretched into the evening in Vienna, the BBC reported.
Mohammad Javad Zarif said he had received "no remarkable proposals to take to Tehran" after meeting US Secretary of State John Kerry for the third time in 24 hours.
Mr Kerry had cancelled plans to leave for Paris to fit in the latest talks.
The clock is ticking down to a Monday deadline for a deal.
Six world powers representing the UN - the US, the UK, France, Germany, Russia and China - want Iran to curb its nuclear programme in return for the lifting of UN sanctions.
They want Iran to demonstrate it is not seeking to build nuclear weapons, in the face of protestations by Tehran that its programme is purely energy-related.
