President Donald Trump announced "major combat operations" against Iran on Feb. 28, with massive joint U.S.-Israeli strikes targeting military and government sites.
Trump set a deadline for Iran to fully reopen the Strait of Hormuz or face broad strikes on its critical infrastructure. Hours before the deadline expired, Trump said he had agreed to suspend planned bombing for two weeks if Iran agreed to reopen the Strait of Hormuz.
But subsequent U.S.-Iran talks in Pakistan failed to reach a peace deal. Trump said that Iran's nuclear program was the key sticking point, and said the U.S. would respond with a blockade of the Strait of Hormuz starting at 10 a.m. ET on Monday.
Israel, meanwhile, has continued ground operations and intense strikes in Lebanon, where it is engaged with the Iran-backed Hezbollah militia. Israeli Prime Minister Benjamin Netanyahu said he supported the ceasefire with Iran, but that Lebanon was not covered by the agreement, despite Iranian protests.
