President Donald Trump says the month-long ceasefire between the US and Iran is on "massive life support," calling it "unbelievably weak."
Iran laid out its demands to end the war and reopen the Strait of Hormuz in a counteroffer sent to the US over the weekend. Trump rejected the proposal, calling it "totally unacceptable" and a "piece of garbage."
Iranian foreign ministry spokesperson Esmail Baghaei responded by saying Tehran's proposals were "responsible" and "generous." Tehran's offer includes an immediate end to the war, a halt to the US naval blockade of Iranian ports, and guarantees of no further attacks on Iran, according to Iran's semi-official Tasnim news agency.
Trump said Iran's leaders are "very dishonourable people" who keep changing their minds. He also accused Iran of going back on an agreement to allow the US to remove its supply of enriched uranium. Israeli Prime Minister Benjamin Netanyahu said Iran's stockpile must be "taken out" and enrichment sites dismantled before the war can end.
Iran continues to block the Strait of Hormuz, driving up world oil prices. The US has been enforcing a blockade of Iranian ports. The war began with massive US-Israeli air strikes on February 28, and a ceasefire took effect last month.
