Negotiations in Vienna between Iran and other world powers will lead the United States back to the 2015 nuclear deal, Israel Defense Intelligence and senior Mossad officials said at a national security cabinet meeting, Axios reported, citing sources at the meeting.

The Israeli government is very concerned about the return of the United States to the nuclear deal and is trying to convince the Joe Biden administration not to ease the pressure on Tehran.

The Mossad mainly briefed the cabinet on the state of the Iranian nuclear program. At the meeting, representatives of military intelligence discussed Iran's actions in the region.

The two intelligence agencies gave similar assessments of the Vienna talks.

US National Security Adviser Jake Sullivan told Fox News that the Vienna talks with Iran were constructive and that there are real attempts to return to mutual compliance with the 2015 nuclear deal.

Sullivan added that the US will not lift the sanctions unless it has clarity and confidence that Iran will fully return to all of its obligations under the 2015 agreement.

Israeli officials said no new political decisions were made at the cabinet meeting, and Israel will continue its dialogue with the Biden administration on talks with Iran.
