DUBAI, United Arab Emirates (AP) — Iran’s top diplomat said the possibility of new negotiations with the United States on his country’s nuclear program has been “complicated” by the American attack on three of the sites, which he conceded caused “serious damage.”

The U.S. was one of the parties to the 2015 nuclear deal in which Iran agreed to limits on its uranium enrichment program in exchange for sanctions relief and other benefits.

That deal unraveled after U.S. President Donald Trump pulled the U.S. out unilaterally during his first term. Trump has suggested he is interested in new talks with Iran and said the two sides would meet next week.

In an interview on Iranian state television broadcast late Thursday, Foreign Minister Abbas Araghchi left open the possibility that his country would again enter talks on its nuclear program, but suggested it would not be anytime soon.

“No agreement has been made for resuming the negotiations,” he said. “No time has been set, no promise has been made, and we haven’t even talked about restarting the talks.”

The American decision to intervene militarily “made it more complicated and more difficult” for talks on Iran’s nuclear program, Araghchi said.

In Friday prayers, many imams stressed Supreme Leader Ayatollah Ali Khamenei’s message from the day before that the war had been a victory for Iran.

Cleric Hamzeh Khalili, who also is the deputy chief justice of Iran, vowed during a prayer service in Tehran that the courts would prosecute people accused of spying for Israel “in a special way.”

During the war with Israel, Iran hanged several people who it already had in custody on espionage charges, sparking fears from activists that it could conduct a wave of executions after the conflict ended. Authorities reportedly have detained dozens in various cities on the charge of cooperation with Israel.

Israel attacked Iran on June 13, targeting its nuclear sites, defense systems, high-ranking military officials and atomic scientists in relentless attacks.

In 12 days of strikes, Israel said it killed some 30 Iranian commanders and 11 nuclear scientists, while hitting eight nuclear-related facilities and more than 720 military infrastructure sites. More than 1,000 people were killed, including at least 417 civilians, according to the Washington-based Human Rights Activists group.

Iran fired more than 550 ballistic missiles at Israel, most of which were intercepted but those that got through caused damage in many areas and killed 28 people.

Israeli military spokesperson Brig. Gen Effie Defrin said Friday that in some areas it had exceeded its operational goals, but needed to remain vigilant.

“We are under no illusion, the enemy has not changed its intentions,” he said.

The U.S. stepped in on Sunday to hit Iran’s three most important strikes with a wave of cruise missiles and bunker-buster bombs dropped by B-2 bombers, designed to penetrate deep into the ground to damage the heavily-fortified targets. Iran, in retaliation, fired missiles at a U.S. base in Qatar on Monday but caused no known casualties.

Trump said the American attacks “completely and fully obliterated” Iran’s nuclear program, though Khamenei on Thursday accused the U.S. president of exaggerating the damage, saying the strikes did not “achieve anything significant.”

There has been speculation that Iran moved much of its highly-enriched uranium before the strikes, something that it told the U.N. nuclear watchdog, the International Atomic Energy Agency, that it planned to do.

Even if that turns out to be true, IAEA Director Rafael Grossi told Radio France International that the damage done to the Fordo site, which was built into a mountain, “is very, very, very considerable.”

Among other things, he said, centrifuges are “quite precise machines” and it’s “not possible” that the concussion from multiple 30,000-pound bombs would not have caused “important physical damage.”

“These centrifuges are no longer operational,” he said.

Araghchi himself acknowledged “the level of damage is high, and it’s serious damage.”

He added that Iran had not yet decided whether to allow in IAEA inspectors to assess the damage, but they would be kept out “for the time being.”
