Iran's supreme leader warned Saturday that his country and the "resistance front" will give an unforgettable lesson to their enemies.

This escalation marks a significant increase in direct military confrontation between Tehran and Washington. The warning follows a lethal strike on American personnel that represents the first U.S. combat deaths since the current conflict began in February [4].

U.S. Central Command said Iranian ballistic missiles and drones targeted a U.S. military base in Jordan [2]. The attack killed two U.S. soldiers [1], left one soldier missing [2], and injured four others [3].

Ayatollah Seyed Mojtaba Hameeni said his warning on Iran's state television [1]. He said the military actions were a necessary response to adversaries, and that Iran and the "resistance front" would ensure the lesson is not forgotten [1].

U.S. officials said the strikes were retaliation for an assault by the Iranian Revolutionary Guard on the base in Jordan [2]. The use of both drones and ballistic missiles indicates a coordinated effort to breach base defenses.

U.S. Central Command did not provide a timeline for the search of the missing soldier. The casualties have heightened tensions in the region as both nations weigh further responses to the breach of military security [2].

"Iran and the 'resistance front' will give an unforgettable lesson to their enemies"

The transition from proxy warfare to direct strikes on U.S. bases by Iranian-led forces suggests a shift in the regional conflict's threshold. By claiming the attack as a 'lesson,' Tehran is signaling a willingness to absorb U.S. retaliation in exchange for establishing a new deterrent against American military presence in Jordan.
