Mojtaba Khamenei says vengeance is "inevitable" for the killing, which happened on the first day of the US-Israeli war on Iran.

Mojtaba Khamenei has not been seen in public since the conflict started in February Iranian Supreme Leader Ayatollah Mojtaba Khamenei has called for revenge for the death of his father and predecessor Ali Khamenei. Vengeance was the "will of the nation", he said in a written statement read out on state TV. It was his first public message since his father's funeral ceremonies began this week. His father was killed in an air strike on 28 February, the first day of the US-Israeli war against Iran. Many Iranians taking part in funeral ceremonies over the past few days carried placards calling for the killing of US President Donald Trump, who on Saturday warned that any such plans would see the US "decimate and destroy all areas" of Iran in response. His son has not been seen in public since before the war, and is rumoured to have been disfigured in the strike which killed his father. "We pledge to avenge the blood of the martyred leader and all the martyrs of these two wars from the criminal and disgraced killers," he was quoted as saying. "The matter depends neither on my personal existence nor on that of other officials. Whether we are present or not, it will come to pass."
