Iran will continue blocking the Strait of Hormuz, the world's busiest oil shipping channel, according to a statement attributed to Iran's new Supreme Leader Mojtaba Khamenei.
His message was broadcast on Iranian state TV, but Khamenei did not appear in person. His message was instead read out by a newsreader.
Iran would "avenge the blood" of Iranians killed in the war with the US and Israel, Khamenei said in the statement, which also warned neighbouring countries to stop hosting US bases.
He was named supreme leader on 8 March after his father, Ayatollah Ali Khamenei, was killed on the first day of the war.
Mojtaba Khamenei lost his wife and a son in the US-Israeli strike on the supreme leader's compound that killed his father. His mother was also reportedly killed in the attack, though one Iranian outlet has since said she is alive.
