TEHRAN, Iran (AP) — Iran is ready to engage in talks on its nuclear program with the United States, but only if Washington takes meaningful steps to rebuild trust, Deputy Foreign Minister Kazem Gharibabadi said Thursday.

Iran is set to meet Friday in Istanbul with Britain, France and Germany, known as the E3 nations, and the European Union’s deputy foreign policy commissioner. They will be the first talks since Iran’s 12-day war with Israel in June, which involved U.S. B-52 bombers striking nuclear-related facilities in Iran.

Gharibabadi said in a social media post Thursday that to enter negotiations, Iran sought “several key principles” to be upheld.

He said these included “rebuilding Iran’s trust — as Iran has absolutely no trust in the United States — avoiding the use of talks as a platform for hidden agendas such as military action, though Iran remains fully prepared for any scenario; respecting and recognizing Iran’s rights under the Non-Proliferation Treaty, including enrichment in line with its legitimate needs; and the lifting of sanctions."

Friday's talks will be held at the deputy ministerial level, with Iran sending Deputy Foreign Minister Majid Takht-e Ravanchi. A similar meeting was held in Istanbul in May.

The stakes are high. European leaders have threatened to trigger a “snapback” mechanism included in a 2015 nuclear deal with Iran, which would reimpose sanctions that were lifted in exchange for Iran accepting restrictions and monitoring of its nuclear program.

The U.K., France and Germany were signatories to the 2015 deal. The U.S. withdrew in 2018 during the first term of President Donald Trump, who insisted the agreement wasn’t tough enough.

Iranian officials have warned that a move to reimpose sanctions would have consequences. Gharibabadi said earlier this week that it could force Tehran to withdraw from key non-proliferation agreements.

In a letter to U.N. Secretary-General António Guterres, Iran's Foreign Minister Abbas Araghchi accused the E3 of hypocrisy, saying they failed to uphold their obligations under the 2015 deal while supporting Israel’s recent strikes on Iran.

In the recent conflict, U.S. B-52 bombers struck Iranian nuclear facilities in support of Israel’s air campaign. Iran responded with missile attacks, including a strike on a U.S. base in Qatar, which President Masoud Pezeshkian insisted was not directed at the Qatari state.

In an interview with Al Jazeera that aired on Wednesday, Pezeshkian said Iran is prepared for another war and accused Israel of attempting to assassinate him during a June 15 meeting of Iran's national security council in Tehran.

Pezeshkian reiterated that Iran’s nuclear program will continue within the framework of international law and insisted the country has no intention of pursuing nuclear weapons.

“Our nuclear capabilities are in the minds of our scientists,” he said, emphasizing Iran’s position that future negotiations must be rooted in mutual respect, not threats.

According to the official judicial news agency Mizan, at least 13 Iranian nuclear scientists were killed during the 12-day war between Iran and Israel.

A spokesman for Iran’s Atomic Energy Organization said Thursday the country’s nuclear industry would recover from the recent attacks by Israel and the United States.

“Our nuclear industry is deeply rooted. What has roots cannot be harmed by attack or pressure — it will grow back and thrive again,” state TV quoted Behrouz Kamalvandi as saying.

The International Atomic Energy Agency, known by the acronym IAEA, reported in May that Iran’s stockpile of uranium enriched to 60% had grown to over 400 kilograms (882 pounds). That material, just below weapons-grade level, remains a central concern for the West.

Despite the growing stockpile, Iran has said it remains open to diplomacy, though it recently suspended cooperation with the IAEA following legislation signed by Pezeshkian.

The road ahead remains uncertain. While European officials say they want to avoid further conflict and are open to a negotiated solution, they have warned that time is running out.
