Iranian state media is saying that the military retaliation is ongoing, with the Islamic Revolutionary Guard Corps (IRGC) Aerospace Force announcing that it launched a heavy ballistic missile attack targeting the US Marine barracks at Camp Titin, located near the Gulf of Aqaba in Jordan - which is at a significant distance, in the country's far southwest corner. State media sources further detail:

According to the IRGC, the strike destroyed multiple military installations and attack helicopters, inflicting heavy casualties on U.S. forces. The operation was executed as the second wave of retaliatory actions under the code name “Ya Rasul Allah.”

And more via state WANA News Agency: "The IRGC stated that the action was carried out in retaliation for a U.S. strike on a residential home during a wedding ceremony in Sirik, which resulted in nearly 50 civilians killed or injured, including children." Iranian claims of US casualties will as usual be hard to verify, but CENTCOM has said no casualties have resulted, per news wires:
