Ammon News - The United States military has moved over 50 fighter jets to the Middle East in the last 24 hours as part of its buildup of air and naval assets near Iran, Axios reported on Tuesday, citing a US official.

A host of F-16, F-22, and F-35 jets were observed heading to the Middle East by independent flight trackers.

The American military buildup comes amid indirect negotiations with Iranian officials, focusing on Iran's nuclear program.

The U.S.-Iran nuclear talks in Geneva on Tuesday "made progress," but "there are still a lot of details to discuss," a U.S. official told Axios.

After negotiations with President Trump's envoys Jared Kushner and Steve Witkoff, the Iranians offered to come back in the next two weeks with detailed proposals "to address some of the open gaps in our positions," the official said.

Earlier Tuesday, Iran's foreign minister Abbas Araghchi claimed that the two sides had agreed on the "guiding principles" for a potential nuclear deal.

Meanwhile, the U.S. is amassing more forces in the Middle East for possible military action against Iran.

In recent days, Trump has sent a second aircraft carrier strike group to the region. More than 50 F-35, F-22 and F-16 fighter jets have moved to the region over the last 24 hours, according to open source flight radar data and a U.S. official.

Araghchi said the talks were "serious, constructive and positive" and claimed "good progress was made compared to the previous meeting, and we now have a clearer path ahead."

"Various ideas were presented and discussed seriously. Ultimately, we were able to reach a general understanding on a set of guiding principles, on the basis of which we will move forward from now on and begin working on the text of a potential agreement. This does not mean that we can reach an agreement quickly, but at least the path has begun," Araghchi told Iranian state television.

Omani foreign minister Badr Albusaidi, who mediated the talks, said that the second round of negotiations ended "with good progress towards identifying common goals and relevant technical issues."

He added that "the spirit of our meetings was constructive."

"Together we made serious efforts to define a number of guiding principles for a final deal," he said. "Much work is yet to be done, and the parties left with clear next steps before the next meeting."

The other side: Asked about the talks, a U.S. official said they went "as expected."

The Iranian foreign minister said both sides agreed to work on drafts of a potential agreement, exchange texts and then determine a date for the third round of negotiations.
