Iran's supreme leader claims attacks on nuclear bases achieved 'nothing' and issues stern warning to the US.

In his first televised address since the ceasefire, Iranian Supreme Leader Ali Khamenei asserted that Iran had "crushed" Israel and dealt a "severe slap" to the United States, while claiming that US attacks on its nuclear facilities had achieved "nothing significant."

They attacked our nuclear facilities, but they did nothing significant.

"I want to congratulate the great Iranian nation, first and foremost for its victory over the Zionist regime," Khamenei said in a written statement published by the official IRNA news agency.

" The Zionist regime was practically knocked out and crushed under the blows of the Islamic Republic ," he added in his address to the nation, adding that it had also "dealt the United States a severe slap in the face."

In his message, the ayatollah did not refer to the ceasefire announced by US President Donald Trump, which went into effect Tuesday morning, nor to the negotiations that Washington says will resume next week.

But he emphasized that the US failed to do "anything significant" against Iran or its nuclear facilities, and that the US president "exaggerated what happened in an unusual way."

"They attacked our nuclear facilities—which, of course, is subject to independent criminal prosecution in international courts—but they did nothing significant ," he said, according to the transcript published by the Revolutionary Guard-linked Tasnim news agency.

In return, Iran attacked the Al-Udeid air base in Qatar, an attack the leader said was downplayed abroad "by saying that nothing had happened, when in fact a major incident had occurred."

Khamenei also threatened to bomb more US bases in the Middle East if Iran is attacked by Washington again.

It may happen again in the future; if an attack occurs, the cost to the enemy and the aggressor will undoubtedly be high.

"The Islamic Republic has access to important US bases in the region and can act against them whenever it deems necessary," Khamenei said in a video broadcast on state television.

"It could happen again in the future; if an attack occurs, the cost to both the enemy and the aggressor will undoubtedly be high ," he added.

The conflict began on June 13, when Israel launched an attack on military and nuclear facilities in Iran, triggering nearly two weeks of missile and drone exchanges between the two countries in a war in which the United States intervened early Sunday morning.

According to official data, the war left at least 28 civilian deaths in Israel and 627 in Iran, and concluded with a US-brokered ceasefire that went into effect last Tuesday.

Iran's Guardian Council approved a plan Thursday for the Islamic Republic to suspend cooperation with the International Atomic Energy Agency ( IAEA), requiring only the signature of the country's president to make this measure effective.

The Guardian Council, made up of six Islamic experts chosen by Supreme Leader Ali Khamenei and six jurists elected by parliament, endorsed the plan approved Wednesday by the Iranian parliament, which calls on the government to suspend cooperation with the IAEA, the official IRNA news agency reported.

With the Council's approval, according to Iran's standard procedure, only President Masoud Pezeshkian's signature would be required for the plan to end cooperation with the IAEA to take effect.

The plan approved yesterday by Parliament entails banning the IAEA from entering Iran and expelling all of its inspectors. Furthermore, Iran's state nuclear agency will be prohibited from sharing information or reports on Iran's nuclear program with the international organization.

Cooperation could resume, the plan estimates, if Iran is assured that its nuclear facilities and scientists—at least eleven have been killed in Israeli attacks—are safe, and if Iran is also given the green light to continue enriching uranium.
