Iran's foreign ministry said on Tuesday that a technical, expert-level nuclear meeting with the United States will be held on Saturday, several days after the date initially planned.
"Following Oman's proposal and the agreement of the Iranian and American delegations, the technical consultative meeting between the two countries, which was to be held as part of the indirect talks between the two sides on Wednesday, has been postponed to Saturday," said foreign ministry spokesman Esmaeil Baqaei.
US President Donald Trump has been seeking an agreement that would curb Iran's nuclear program, which Washington believes is aimed at developing a nuclear weapon.
American and Iranian officials have so far held two rounds of talks, one in Muscat and the second in Rome.
Trump has threatened to bomb Iran unless a deal is reached; Iran denies seeking atomic weapons.
