An Iranian military commander has warned the United States and Israel against any attack on Iran as it prepares for the state funeral of Supreme Leader Ayatollah Ali Khamenei, who was assassinated in airstrikes on the first day of the war, Reuters reports.

“We warn the enemies of Iran, especially the US and the Zionist regime (Israel), to avoid any miscalculation and to think about the harsh retaliation our armed forces would make to any threat and aggression against our country, Ali Abdollahi, commander of Khatam al-Anbiya Central Headquarters, said in a statement carried by state media.

Funeral processions for Khamenei will begin on July 4 in Tehran and conclude on July 9 with his burial in his hometown of Mashhad, with additional ceremonies planned in Qom and Iraq in between these dates.
