Iran's foreign minister today the United States must take political decisions to end the current "deadlock" at talks in Vienna over his country's disputed nuclear programme.
Mohammad Javad Zarif, quoted by the official IRNA news agency, said such decisions were needed "to see what the solutions are" and to decide "what solution can pave the way towards an agreement".
Zarif's comments came after more signs that the negotiations between Iran and six world powers are a long way from reaching a deal by the July 20 deadline.
His remarks were released just before US Secretary of State John Kerry told reporters in the Austrian city that Iran's nuclear capacity must be cut, a step that Tehran has repeatedly ruled out.
Despite the impasse, American and Iranian diplomats have said they remain focused on a deal to resolve the decade-long standoff over Iran's nuclear ambitions, which the West suspects mask a drive for the bomb.
Iran insists its enrichment of uranium is for entirely peaceful purposes in the form of nuclear power.
