Iran’s new Supreme Leader, Ayatollah Mojtaba Khamenei, declared over the weekend that his predecessor’s death must be avenged, a statement that further inflamed already tense relations with Washington. The remarks came during funeral services for his father, Ali Khamenei, who was killed in February by US–Israeli airstrikes. In response, President Donald Trump posted on Truth Social that the United States has a thousand missiles ready to strike Iran, with many more prepared, if the Iranian government follows through on what he described as widespread threats to assassinate him. The warning followed a week of renewed hostilities and coincided with new US Treasury sanctions targeting an Iranian financial facilitator accused of embezzlement. Oil prices rose roughly four percent amid the escalating confrontation.
