The Hebrew account opened by Iranian leader Ayatollah Ali Khamenei on social media platform

The last message on Sunday read: “The Zionist regime has made a mistake and miscalculated regarding Iran. We will make the country understand the power, ability, initiative and desire of the Iranian nation.”

On Saturday, the first Hebrew post appeared with the text: “In the name of Allah the Merciful.” Both posts came after Israeli attacks on Iranian military targets last week.

On his main account on X, Khamenei often posts in Hebrew, often using strong language against Israel.

Khamenei had said Israel’s airstrikes on Iran should not be increased or downplayed. While Israel is keen to increase the impact of its actions against Iran, Khamenei said on Sunday, adding that it would also not be right for Iran to dismiss the attacks as insignificant, CNN reported.

“They are making a miscalculation regarding Iran,” he said in a comment on his website. “They have still failed to fully understand the power, capability, ingenuity and determination of the Iranian people. We have to make them understand these things.”

Iran said Israeli airstrikes on its military sites killed two soldiers on Saturday, after Israel simultaneously attacked missile production facilities, surface-to-air missiles and other “air capabilities”.

It later said the airstrike had “terminated” its response to the October 1 Iranian missile attack, saying the warplanes had returned safely and the mission had been “accomplished”. Iran’s air force confirmed attacks on military bases in Tehran, Khuzestan and Ilam provinces that “caused limited damage.”
