Iran's armed forces chief of staff and its top security official warned on Sunday that the United States and Israel would face a more severe military response to any further action.
Major General Ali Abdollahi, chief of staff of Iran's armed forces, said any new US or Israeli "miscalculation" would bring a harsher reply, according to Xinhua, China's state news agency. Xinhua said his statement was carried by Iranian media.
Xinhua quoted him as saying: "You should know that any new miscalculation will be met with responses that are different from and far more severe than those of the past." He also said that if the US and Israel could carry out their threats, they would have done so already.
Separately, Mohsen Rezaei, Secretary of Iran's Supreme National Security Council, posted on X on Sunday that the armed forces had prepared a plan more devastating than in the 12-day and 40-day wars, according to Tasnim, an Iranian state-linked news agency.
Tasnim said Mr Rezaei was responding to repeated threats from US and Israeli officials in recent days. He said those threats did not change the realities on the ground.
Xinhua's translation of his words was: "Iran's armed forces have prepared a more devastating plan than the 12- and 40-day wars for a new adventure." It also reported that he said Iran's new operational plan would not follow rules the other side knew.
The websites Newscord and Sunnafiles, which repeated Mr Abdollahi's statement, reported further remarks from him. They said he stated that US and Israeli slogans about overthrowing or partitioning Iran would have been put into practice if they had been capable of it.
The same websites said he told them the next "roar", or explosion, would be closer and could not be intercepted or traced. Tehran Telegraph has not been able to check these remarks against an Iranian primary source.
Xinhua said the Iranian statements followed comments by US President Donald Trump in an interview with Newsmax on Thursday night. It said he told the channel that Washington may have to target "Pickaxe Mountain".
Xinhua described the site as claimed to be linked to Iran's nuclear programme. The text available to Tehran Telegraph did not include the rest of Mr Trump's remarks or any Israeli statements.
No response from the US or Israeli governments to Mr Abdollahi's or Mr Rezaei's statements had been reported. The statements are the positions of the Iranian officials, and the claims in them are their own.
Xinhua also reported that Tehran announced on Sunday plans for a regional authority to oversee digital data flows. It gave no further detail in the text seen by Tehran Telegraph.
Israel and Iran fought a 12-day war in June 2025, in which the US was also involved. Iranian officials have referred to it since. An IRNA report from 16 June 2025 showed President Masoud Pezeshkian warning of "more painful" responses during that conflict.
According to a text on News Beep based on Xinhua reporting, Israel and the US launched joint attacks on Tehran and other Iranian cities on 28 February 2026. That text refers to the conflict that followed as the 40-day war.
It said Iran responded with missile and drone attacks on Israel and on US bases and assets in the region. It added that Iran also tightened its control of the Strait of Hormuz.
The same text said a ceasefire was reached on 8 April. It said Iran and the US then signed a memorandum of understanding on 18 June on ending the war "on all fronts".
It also said Iran still had a seven-day plan to reopen the Strait of Hormuz "on the table" in October. The text did not make clear whether that was an Iranian offer or part of an agreement.
The Supreme National Security Council is Iran's top security decision-making body. The chief of staff of the armed forces commands the military. Tasnim and Xinhua named Mr Rezaei and Mr Abdollahi as holding these posts.
No scheduled talks between Iran and the US had been reported in the sources reviewed by Tehran Telegraph. It was not clear whether the memorandum or the Hormuz plan was being put into effect.
