“The Obama administration signaled impatience with Iran after the Tehran government ignored a Friday deadline to respond to a U.N.-brokered deal aimed at easing concerns over its nuclear program. Iran has promised a reply by next week,” Voice of America informs Oct. 24.

According to the source, “U.S. officials say they're willing to wait a few more days for an Iranian response to the nuclear proposals, but they say the Obama administration is looking for concrete action and does not have unlimited patience.”

“The comments from the State Department came after Iran failed to provide a final response Friday to a proposal brokered by the United Nations nuclear watchdog agency under which Tehran would ship abroad much of the low-enriched uranium it has produced in an enrichment effort that has drawn international concern,” VOA reads.
