Iran resumes attacks in Strait of Hormuz after lull, U.S. officials say
Context
Iran's military fired at least two missiles at commercial ships transiting the Strait of Hormuz on Monday night, two U.S. officials tell Axios. Why it matters: The reported attack took place after a one-week agreement between the U.S. and Iran on halting attacks in the strait expired. The resumption of Iranian attacks put the memorandum of understanding (MOU) that was signed less than three weeks ago at risk of unraveling. The U.S. is likely to retaliate with strikes against Iranian targets. Driving the news: The U.K. maritime trade operation said on Monday it has received a report from a tanker that was traveling south near the Omani coast in the strait of Hormuz and was hit by an unknown projectile causing a fire. The U.S. official said another commercial ship was hit by an Iranian missile. Both vessels suffered significant damages, but no casualties, the U.S. official said. State of play: A round of indirect talks between the U.S. and Iran in Doha last week ended without much progress on the issue of the strait of Hormuz. Editor's note: This is a breaking news story.

What it means
Iran's resumption of missile strikes on commercial shipping in the Strait of Hormuz — after a diplomatic pause expired — is a genuinely new escalation beyond the ongoing Israel-Lebanon conflict and has historically been associated with sharp spikes in Brent crude due to direct supply-route risk. Tanker operators face elevated war-risk premiums, while the prospect of U.S. retaliation tends to support defense stocks. The collapse of the MOU and stalled Doha talks suggest this is not a brief flare-up.
