US president calls Iranian response ‘totally unacceptable’ while Tehran says it will retaliate against any new US strikes or foreign warships in strait of Hormuz

Trump calls Iran’s response to peace plan ‘totally unacceptable’ as ceasefire frays

The US parameters for nuclear talks reportedly included a moratorium on Iranian nuclear enrichment for up to 20 years; the transfer overseas, possibly to the US, of Iran’s stockpile of highly enriched uranium (HEU), which could be used to make nuclear warheads; and the dismantling of Iranian nuclear facilities.

According to the Wall Street Journal, the Iranian counter-proposal suggested a shorter moratorium, the export of part of the HEU stockpile and the dilution of the rest, and refusal to accept the dismantling of facilities.

The Israeli prime minister, Benjamin Netanyahu, had earlier warned the war would continue as long as Iran had a stockpile of HEU.
