The Pentagon has reported 19 U.S. military deaths linked to the Iran war. The Army identified Capt. Bianca C. Wilkerson, 37, as the latest casualty, who died on September 18 from a non-combat medical emergency while supporting operations in Doha, Qatar.

U.S. officials suggest the actual number of military deaths in the region is higher, with at least 22-23 fatalities reported since the Iran conflict began, some not included in the Pentagon's public database, according to WaPo.
