President Donald Trump warned Iran on Truth Social after mourners at the funeral of slain Supreme Leader Ayatollah Ali Khamenei called for his assassination, and following several days of US airstrikes triggered by Iranian attacks on three ships in the Strait of Hormuz. Trump said his military had many weapons prepared to strike if Iran carried out its threats. The warning came as senior US officials pressed Tehran to publicly guarantee the strait remains open, but Iran refused, insisting it controls the waterway and may charge vessels—departing from its long-standing status as an international passage. The standoff threatens a fragile wartime ceasefire and global energy flows, with about a fifth of traded oil and gas normally passing through the strait.
