Iran welcomed as "useful" its first round of nuclear talks with the major powers since the two sides gave themselves another seven months to strike a deal.
"We had intensive and useful discussions," Iran's lead negotiator, deputy foreign minister Abbas Araqchi, told state television after a two-hour meeting in Geneva yesterday.
"All issues were discussed. We'll have a new meeting in a little under a month."

The powers, which also include Britain, China, France, Germany and Russia, held formal talks with the Iranians in Vienna last month.
They failed to meet a November 24 deadline for a comprehensive deal on reining in Iran's nuclear programme in exchange for an easing of crippling Western sanctions.
All parties agreed to give themselves seven more months -- until June 30 -- to strike a deal, although they said they hoped to have the broad outlines hammered out by March.
A final agreement is aimed at ensuring Tehran will never develop nuclear weapons under cover of its civilian activities.
Iran denies that it is seeking the bomb and insists its nuclear programme is for peaceful purposes only.
