U.S. stock futures fall, oil surges as Trump calls Iran’s latest offer to end war ‘totally unacceptable’

U.S. stock-index futures fell and oil prices rose after President Donald Trump rejected Iran's response to end the war, calling it 'totally unacceptable'. The rejection led to a decline in U.S. stock futures and a surge in oil prices on Sunday. This development indicates ongoing tensions between the U.S. and Iran.
