A senior Iranian nuclear negotiator has urged world powers to find a "common position" to achieve a "balanced" final nuclear deal with the Islamic republic as a deadline for negotiations looms.
A report by Iran's state-run Press TV satellite news channel quoted Abbas Araghchi making the comment about talks between Iran and the six-nation group including the US, Russia, China, the UK, France and Germany.
The US and Iran broke off nuclear negotiations in Lausanne, Switzerland, on Friday for consultations, but they are to resume the make-or-break talks on Wednesday.
The talks seek a permanent deal to cap Iran's nuclear programme in exchange for the easing of economic sanctions.
Iran said its nuclear programme is for peaceful purposes. The west fears it could allow Iran to build an atomic bomb.
