Iranian official media have confirmed the death of Lieutenant General Abdolrahim Mousavi, Chief of the General Staff of the Armed Forces, and Major General Aziz Nasirzadeh, Minister of Defence, in the US-Israeli attacks.

They have also confirmed the death of Admiral Ali Shamkhani, who was a key advisor to Ayatollah Ali Khamenei and secretary of Iran’s Defense Council, and Major General Mohammad Pakpour, the Commander-in-Chief of the elite Iran Revolutionary Guards Corp (IRGC). Both were both killed on Saturday, said state affiliated news agency IRNA.

Ali Shamkhani has been a towering figure in the Iranian power structure for decades. He served as country’s top national security officials for a decade from 2013, and before that served in a number of important roles, including in the Islamic Revolutionary Guard Corps (IRGC) and the ministry of defense.

Shamkhani, who once ran for the presidency in 2001, had been a rising star of Iranian diplomacy, well known in foreign-policy circles in Washington and Europe.

Some media reports said about 40 top leaders of Iranian establishment were killed in the attacks.

The US will hit Iran "with a force that has never been seen before" if the Middle East nation retaliates, Trump said on Sunday.

"Iran just stated that they are going to hit very hard today, harder than they have ever been hit before," Trump said in a post on Truth Social.

He added, "THEY BETTER NOT DO THAT, HOWEVER, BECAUSE IF THEY DO, WE WILL HIT THEM WITH A FORCE THAT HAS NEVER BEEN SEEN BEFORE!"
