Iran media reported that its response included proposals for an immediate end to the war on all fronts, a halt to a US naval blockade and guarantees of no further attacks on Iran.
Trump posted on the Truth Social platform: "I have just read the response from Iran's so-called "Representatives." I don't like it — TOTALLY UNACCEPTABLE."
US proposals are reported to include a suspension on Iranian nuclear enrichment, the lifting of sanctions, and restoring free transit of shipping through the Strait of Hormuz.
Iran has continued to block the Strait of Hormuz - leading to a rise in world oil prices. The US, for its part, has been enforcing a blockade of Iranian ports to exert pressure on Tehran to agree to its terms - a move that has infuriated Iran.
