Iran's supreme leader warns Trump of 'irreparable harm' if US joins Israeli strikes
BBC update
IRAN'S supreme leader warns Donald Trump of "irreparable harm" if the US military intervenes in Tehran's conflict with Israel.
Ayatollah Ali Khamenei says in a message on state television that Iran will not surrender, following an earlier warning from the US president.
Trump is considering joining Israel's strikes on Iranian nuclear facilities, the BBC's US partner CBS News reports.
The conflict has now reached a critical juncture - what Trump decides could shape what happens next in the Middle East, writes Frank Gardner.
Israel hit two Iranian centrifuge production sites overnight, the UN's nuclear watchdog says, while Iran says it targeted Israel with a hypersonic missile.
