Iran carried out a missile strike overnight Tuesday on a military base in Azraq, Jordan, that is used by American forces, causing minimal damage and no deaths, according to two U.S. officials who spoke on Wednesday. While equipment damage was limited, the officials cautioned that some U.S. service members might report symptoms of traumatic brain injury in the days following the attack, a common consequence of such strikes.

The incident comes amid escalating tension and a pattern of retaliatory actions between the United States and Iran. On Tuesday, the U.S. military reported that it had destroyed five Iranian oil tankers in response to what it described as attempted Iranian strikes on a U.S. Navy warship.

In retaliation, Iran's Islamic Revolutionary Guards Corps (IRGC) launched the missile attack on the Jordanian base, which the IRGC described in state media as a “punitive operation” with a commitment to continued actions.

The Jordanian military reported intercepting 18 of the 20 missiles fired at the base, stating that the two remaining projectiles landed in unpopulated areas. Despite these interceptions, the two U.S. officials confirmed that the Azraq base was struck.

Since the onset of the conflict over six months ago, 18 American service members have been killed, with numerous others injured. The Pentagon has generally limited information on U.S. casualties unless they are severe, citing operational security concerns.

This latest attack is the most recent in a series of tit-for-tat exchanges between Washington and Tehran, underscoring the ongoing volatility in the region. Both U.S. and Iranian forces remain engaged in a cycle of actions and responses, raising concerns about further escalation.
