A senior US official said that Iran has abandoned some of the basic conditions for reviving the nuclear agreement, which aims to restrict Tehran's nuclear program, while the European Union's High Commissioner for Foreign and Security Policy Josep Borrell announced the approval of most of the parties to the European proposal to revive the nuclear agreement.

The US official told Reuters that the main demands that Iran has abandoned include its insistence that the International Atomic Energy Agency inspectors end some investigations related to its nuclear program, which increases the possibility of reaching an agreement.

The official, who spoke on condition of anonymity due to the sensitivity of the matter, added that although Tehran says Washington has to make some concessions, it has given up some of its basic demands.

"They came back last week and basically abandoned the main obstacles to a deal," he said.

In the same context, the European Union's High Commissioner for Foreign and Security Policy Josep Borrell said that most of the countries participating in the nuclear talks with Iran agree to the European Union's proposal in the Iranian nuclear negotiations file.

As for the Iranian response to the European proposal submitted by Iran last week, the European Union foreign policy coordinator Josep Borrell described the response as reasonable.

Borrell suggested a meeting in Vienna this week as part of talks to revive the agreement.

On the other hand, today, Tuesday, in Washington, US National Security Adviser Jake Sullivan will meet with his Israeli counterpart, Eyal Holata, to discuss talks to revive the Iranian nuclear agreement, in addition to negotiations to demarcate the maritime borders between Israel and Lebanon, the Israeli occupation authorities’ closure of Palestinian civil rights institutions, and the investigation into the assassination of colleague Shirin Abu sane.

While Washington said that it is working to respond to what Iran has provided as soon as possible;

Russia, through the Russian envoy to international organizations in Vienna, Mikhail Ulyanov, accused the United States of following a usual pattern with approaching what he described as the finish line, but this is not a reason for pessimism, as he put it.
