US Deputy Secretary of State Wendy Sherman told Al Jazeera that Washington strongly supports the resumption of the Vienna negotiations on Iran's nuclear file, but stressed that her country may resort to other options, if Tehran does not comply with the terms of the 2015 nuclear agreement.

"We are very much in favor of resuming where we left off in these negotiations, and returning to mutual compliance," Sherman said in an exclusive interview. "We hope that Iran will come to those negotiations in good faith, because I think we can make very rapid progress."

"If Tehran does not do this and continues with its nuclear program, we will look at what is called 'Plan B', and what we can do to ensure that Iran does not get a nuclear weapon," she said.

These statements come after Iran and the European Union - which is coordinating those negotiations - said on Wednesday that all parties had agreed to return to the Austrian capital on November 29.

The Vienna negotiations began last April, and stopped with the election of a new president in Iran last June.

Yesterday, Thursday, Iranian President Ebrahim Raisi said that his country seeks to lift and nullify all US sanctions.

"We will not leave the negotiating table, but we will not retreat an iota from the interests of our nation," he added.

In the context of the Iranian-American tension, the two sides presented two contradictory accounts last Wednesday about an incident in the Sea of ​​Oman dating back several days, as Tehran announced the thwarting of an American attempt to confiscate Iranian oil, which Washington denied.
