President Cristina Fernandez has portrayed Argentina's spy agency as sinister, accountable to no one, and possibly responsible for the mysterious death of a prominent prosecutor in his Buenos Aires apartment.

Iran said talks with France, Germany and Britain on Thursday on its nuclear program were "promising" but more work was needed to settle the 12-year standoff, the official IRNA news agency reported.

Key Democratic U.S. senators said on Tuesday they would put off supporting new Iran sanctions for at least two months, after a threat by President Barack Obama to veto a bill he said could scuttle talks with Tehran over its nuclear program.
