Donald Trump says a US blockade of Iranian ports will begin on Monday at 10:00 ET (14:00 GMT).
US Central Command says it will “not impede” ships sailing through the Strait of Hormuz to or from other countries – despite this, oil prices jump above $100 a barrel.
Iran’s parliament speaker says the country will not “surrender under threats” and the Islamic Revolutionary Guard Corps says military vessels approaching the strait will be “dealt with severely”
If it goes ahead, the diplomatic ramifications of this blockade could be huge, our correspondent writes
Meanwhile, the Pope responds to criticism levelled at him by Trump, saying he has “no intention to debate” the war with the US president – Trump had accused the pontiff of being “terrible for foreign policy”
Weekend peace talks between the US and Iran ended without a deal – Trump says they failed because Iran wouldn’t “give up its nuclear ambitions”; Iran’s foreign minister blames “shifting goalposts” from the US.
