Iran has been given a proposal for the next round of indirect nuclear negotiations with the United States, the country's Deputy Foreign Minister Kazem Gharibabadi said on Tuesday.

"We have received a proposal regarding the next round of indirect talks between Iran and the US, and it is under review," Gharibabadi noted, without revealing further details.

The day before, the Wall Street Journal reported that the talks could take place next weekend in Rome, while the United Arab Emirates-based The National said Iran rejected Oman's offer for the new round of negotiations due to the US' insistence on "zero enrichment."
