World powers fearful of scuttling negotiations are offering Iran new, though meager, sanctions relief if Tehran curbs its nuclear program. But they warned Monday that it's unlikely that any compromise will be reached soon.
Negotiators set low expectations for the latest round of high-level diplomatic talks to begin Tuesday, the first since last June's meeting in Moscow.
The Obama administration has not ruled out the possibility of military intervention to prevent Iran from acquiring a nuclear weapon. And Israel has threatened it will use all means to stop Iran from being able to building a bomb.
Tehran maintains it is enriching uranium only to make reactor fuel and medical isotopes, and insists it has a right to do so under international law
