Iran’s supreme leader warns the United States of “unforgettable lessons” if it continues attacks on Iran, according to reporting ahead of a new incident involving U.S. forces in the region. Separately, the U.S. military says an attack on a base in Jordan results in casualties among U.S. personnel: two service members are killed and a third is listed as missing. The reports state that the announcement comes shortly after the supreme leader’s warning. The accounts link the timing of the Iranian warning and the U.S. military’s casualty update, but they do not provide detailed, corroborated information in the available summaries about the specific party responsible for the attack in Jordan or the circumstances leading to the missing service member. The information provided centers on the Iranian leader’s message to the United States, and the U.S. military’s confirmation of two deaths and one missing person following the attack at a Jordanian base involving U.S. service members.
