Delegations of U.S. Secretary of State John Kerry, Britain's Foreign Secretary Philip Hammond, Russian Foreign Minister Sergei Lavrov, Iranian Foreign Minister Javad Zarif, German Foreign Minister Frank-Walter Steinmeier, French Foreign Minister Laurent Fabius, EU High Representative Catherine Ashton, Chinese Foreign Minister Wang Yi sit around the negotiations table during their meeting in Vienna November 24, 2014.
Western officials said they were aiming to secure an agreement on the substance of a final accord by March but that more time would be needed to reach a consensus on the all-important technical details.
"We have had to conclude it is not possible to get to an agreement by the deadline that was set for today and therefore we will extend the JPOA to June 30, 2015," British Foreign Secretary Philip Hammond told reporters at the end of the talks.
He was referring to the so-called Joint Plan of Action, an interim deal agreed between the six and Iran a year ago in Geneva, under which Tehran halted higher level uranium enrichment in exchange for a limited easing of sanctions, including access to some frozen oil revenues abroad.
Hammond said the expectation was that Iran would continue to refrain from sensitive atomic activity.
He added that Iran and the powers "made some significant progress" in the latest round of talks, which began last Tuesday in the Austrian capital. Hammond said that there was a clear target to reach a "headline agreement" of substance within the next three months and talks would resume next month.
