The number of Americans wounded in the Iran war has grown beyond 300, with more than two dozen troops injured this week from attacks on a Saudi air base. Iran fired six ballistic missiles and 29 drones at Saudi Arabia’s Prince Sultan air base in an attack Friday that injured at least 15 troops, including five seriously. That's according to two people briefed on the matter who weren't authorized to discuss it publicly and spoke on the condition of anonymity. Meanwhile, a Navy ship carrying about 2,500 Marines has arrived in the region. The U.S. military presence already had included two aircraft carriers, several other warships and some 50,000 troops.
