The United States has continued airstrikes against Iranian targets while Tehran expanded its retaliation and declared the Strait of Hormuz closed.

This escalation threatens global energy security and increases the risk of a wider regional conflict as both nations target military infrastructure in the Persian Gulf.

U.S. military operations have hit hundreds of targets [3] within Iranian territory, including sites in Bandar Abbas and Qeshm Island [1]. U.S. officials said the strikes are retaliation for Iranian attacks that killed three American service members [2].

President Donald Trump said Iran would "pay" if any American troops are killed. He said there will likely be more U.S. deaths as Iran strikes to continue until all goals are achieved [2].

Tehran has responded by broadening its offensive. The Iranian government and Revolutionary Guards launched attacks on U.S. bases located in Kuwait, Qatar, and Bahrain [1]. A spokesperson for the Revolutionary Guards said the latest attacks are retaliation for U.S. actions and that Iran will keep the Strait of Hormuz closed [4].

While the Iranian government maintains the strait is closed, some reports focus on explosions in Bandar Abbas and Qeshm Island without confirming a total blockade [1]. The Strait of Hormuz is a critical chokepoint for global oil shipments, a fact reflected in recent market volatility.

Brent crude prices rose 3.3% to $78.50 per barrel following the developments [5]. Iran said its actions are intended to pressure the U.S. to cease interference in the region [2].

Iran would "pay" if any American troops are killed.

The closure of the Strait of Hormuz, if sustained, represents a significant escalation in the US-Iran conflict. Because a vast majority of the world's seaborne oil passes through this narrow waterway, any prolonged disruption likely triggers global price spikes and forces international naval interventions to ensure the freedom of navigation.
