Iran and six world powers meet in Moscow on Monday for a new round of nuclear talks, with the clock ticking on international diplomatic efforts to persuade Tehran to curb activities that could be used to make atomic arms.
Diplomats from several nations have depicted the talks as crucial. They say that it will likely be the last in a series and that if negotiators fail to make headway in persuading Tehran to stop higher-grade-uranium enrichment, it's unclear if or when new talks would occur.
Iran insists that all of its nuclear activities are peaceful.
