The spokesperson Esmaeil Baqaei does not explain the conversations as completely finished.
It is still unclear what we decide to do with the conversations on Sunday, he says.
Earlier in the week, before the Israeli attack on Iran, it was announced that new nuclear energy talks were planned to be held between the US and Iran on Sunday in the Omani capital Muscat.
US President Donald Trump says that the latest developments in the Middle East are a possible "second chance" for Iran's leadership to avoid more destruction, and urges the country to quickly reach a nuclear energy agreement.
The latest round of negotiations between the countries ended on May 23 without major success.
