Iran remains open to diplomacy to save its 2015 nuclear deal with world powers but has "no hope" in the international community, Iran's Foreign Ministry spokesman Abbas Mousavi said.
"We have no hope nor trust in anyone nor any country but the door of diplomacy is open," Mousavi said.
Spokesman for Iran's nuclear agency Behrouz Kamalvandi said that the country might consider going to 20% enrichment or higher as its third step, if the material is needed, abc news reported.
On Monday, Iran started enriching uranium beyond the limit of 3.67%. Enriched uranium at the 3.67% level is enough for peaceful pursuits but is far below weapons-grade levels of 90%.
