A senior Iranian military commander warned the United States and Israel on Thursday against launching any attack on Iran as the country prepares for the official funeral of Supreme Leader Ayatollah Ali Khamenei, who was killed in airstrikes on the first day of the war.

Ali Abdollahi, commander of Iran’s Khatam al-Anbiya Central Headquarters, warned Washington and Israel against any “miscalculation,” saying Iran’s armed forces would deliver a “strong response” to any threat or aggression against the country.

Khamenei’s funeral ceremonies are scheduled to begin on July 4 in Tehran and conclude on July 9 with his burial in his hometown of Mashhad. Additional memorial events are also planned in Qom and Iraq during the same period.

Iranian Foreign Minister Abbas Araghchi issued a similar warning on Wednesday, saying Tehran would respond immediately and forcefully to any threat against its people or leadership, following Israeli Defense Minister Israel Katz’s remarks describing Iran’s current supreme leader, Mojtaba Khamenei, as “a target for assassination.”
