The first post from Iranian Supreme Leader Ayatollah Ali Khamenei's X account after his confirmed death warned of serious repercussions to the 'big mistake' the 'zionist regime' made.
The post, which came a week after Khamenei was killed in a joint US-Israel military strike, said 'the Zionist regime has made a big mistake, and its consequences will make the regime desperate, by God's grace.'
The message appeared to be a warning directed at Israel, amid escalating tensions in the Middle East following the killing of the long-time cleric.
Khamenei, 86, was killed in a joint US-Israel military strike on Iranian territory that also targeted senior Iranian officials and military figures.
The operation came after US President Donald Trump authorised the campaign, with Israeli aircraft reportedly dropping dozens of precision-guided munitions on the complex.
Following Khamenei's death, Iranian authorities announced a three-day farewell ceremony for the late leader at Tehran's Imam Khomeini Mosalla prayer ground.
