Two U.S. service members were killed and a third went missing Friday when Iran attacked a military base in Jordan — the first American combat deaths from Iranian fire since an April ceasefire collapsed. The incident marks a dangerous escalation in the now-active U.S.-Iran war that began in late February 2026, with both sides expanding strikes across the region. U.S. forces began retaliatory strikes early Sunday, signaling this cycle of escalation is likely to continue.
