The U.S. military launched air strikes against about 140 targets in Iran overnight on July 11-12 in response to an attack on a commercial vessel [1].

This escalation marks a significant breakdown in regional stability, as the U.S. government now considers a previous peace agreement void. The strikes target Iranian infrastructure following a breach of maritime security in one of the world's most critical shipping lanes.

U.S. Central Command said it hit the targets after Tehran attacked a ship in the Strait of Hormuz [1]. A spokesperson for the U.S. Department of Defense said the military is striking Iran in response to the attack on a civilian vessel [2].

The military action follows a period of heightened tension in the region. According to reports, Iran announced it would close the Strait of Hormuz again on Sunday, July 7 [3]. The Strait is a vital corridor for global oil shipments, and any disruption threatens international energy markets.

President Donald Trump said the U.S.-Iran cease-fire is "over" after strikes resumed in the Strait of Hormuz [4]. The 2026 cease-fire agreement had previously served as a buffer against direct military confrontation between the two nations.

While some reports characterize the strikes as a limited response, the scale of the operation — hitting approximately 140 sites [1] — suggests a broad effort to degrade Iranian capabilities. The U.S. maintains that the retaliation was necessary to protect shipping and uphold international maritime law.

Iran has not yet provided a detailed official response to the overnight strikes, though the incident follows a series of provocative moves in the Persian Gulf. The U.S. military remains on high alert in the region as the situation develops.

The termination of the 2026 cease-fire removes a primary diplomatic constraint on U.S. and Iranian military engagement. By striking 140 targets, the U.S. is signaling a shift from containment to active deterrence, which increases the risk of a wider regional conflict that could disrupt global energy supplies via the Strait of Hormuz.
