ShareSaveAdd as preferred on GoogleBBCUS President Donald Trump has warned Iran the "clock is ticking" as talks to bring the war to an end have stalled.
"They better get moving, FAST, or there won't be anything left of them," he wrote on his Truth Social platform. "TIME IS OF THE ESSENCE!"
The message came as the president was due to speak with Israeli Prime Minister Benjamin Netanyahu on Sunday.
Trump warned earlier this week that the ceasefire agreed with Iran was on "massive life support" after rejecting Tehran's demands to end the war.
Trump had labelled the Iranian counter to US proposals "totally unacceptable".
Esmail Baghaei, an Iranian foreign ministry spokesperson, insisted it was "responsible" and "generous".
According to Iran's semi-official Tasnim news agency, it includes an immediate end to the war on all fronts - a reference to the continued Israeli attacks against Iran-supported Hezbollah in Lebanon - a halt to the US naval blockade of Iranian ports, and guarantees of no further attacks on Iran.
It also reportedly includes a demand for compensation for war damage and an emphasis on Iranian sovereignty over the Strait of Hormuz.
