US, Iran study ceasefire plan as Trump's 'hell' warning nears deadline

On the eve of a U.S. deadline, Washington and Tehran weighed a Pakistani-brokered plan for an immediate ceasefire and talks within 15 to 20 days, as Iran rejected pressure to reopen the Strait of Hormuz. President Donald Trump threatened more strikes if no deal is reached by Tuesday 8 p.m. ET. Tehran said talks cannot proceed under ultimatums and dismissed earlier U.S. demands. New attacks hit Iranian energy sites; Israel claimed killing a senior Guards intelligence chief. Markets shifted on ceasefire hopes, while the war's toll rose across Iran, Israel and Lebanon.
