Tehran, March 1 : Iran's state media confirmed Sunday that Supreme Leader Ayatollah Ali Khamenei was killed in US-Israeli attacks. The Iranian government announced a 40-day mourning period after the report of the leader's death.

Iranian state media confirmed on Sunday that Khamenei was killed in US-Israel airstrikes.

Four relatives of Khamenei, including his daughter, grandchild and son-in-law, were also killed in the US-Israeli strikes, reported Iran's Fars News Agency, citing sources.

Taking to Truth Social, Trump announced that the Iranian Supreme Leader was killed in joint US-Israeli strikes, calling it the "single greatest chance" for Iranians to reclaim control of their country.

â??Khamenei, one of the most evil people in History, is dead,â?? Trump said in a statement. He called it â??Justice for the people of Iranâ?? and for â??all Great Americans, and those people from many Countries throughout the World, that have been killed or mutilated by Khamenei and his gang of bloodthirsty THUGS.â??

Trump said Khamenei â??was unable to avoid our Intelligence and Highly Sophisticated Tracking Systems and, working closely with Israel, there was not a thing he, or the other leaders that have been killed along with him, could do.â??

Meanwhile, Trump said the massive military campaign against Iran will continue.

"The heavy and pinpoint bombing, however, will continue, uninterrupted throughout the week or, as long as necessary to achieve our objective of PEACE THROUGHOUT THE MIDDLE EAST AND, INDEED, THE WORLD!" Trump said in the post.

Trump repeated his earlier call for Iran's Islamic Revolutionary Guard Corps, armed forces and police to lay down their weapons in exchange for immunity.

In an interview with NBC News earlier on Saturday, Trump said that "most" of Iran's senior leadership is "gone," saying: "The people that make all the decisions, most of them are gone."

Israeli media on Saturday also reported that Khamenei was killed in US-Israeli attacks and his body has been found.
