May 7 (UPI) -- U.S. Central Command said that forces struck at Iranian military sites responsible for "unprovoked" missile, drone and boat attacks on U.S. warships Thursday in the Strait of Hormuz.

The U.S. attacks were on ports near the strait, Bandar Abbas and Qeshm, CBS News reported. It said three U.S. warships in the strait (the USS Truxtun, the USS Rafael Peralta and the USS Mason, according to CNN) were attacked by Iran but not struck.

The sites targeted included "missile and drone launch sites, command and control locations; and intelligence, surveillance and reconnaissance nodes," Central Commend said, CNN reported

President Donald Trump promptly took to social media to post a warning to Iran.

"Missiles were shot at our Destroyers, and were easily knocked down," he wrote. "Likewise, drones came, and were incinerated while in the air. They dropped ever so beautifully down to the Ocean, very much like a butterfly dropping to its grave! A normal Country would have allowed these Destroyers to pass, but Iran is not a Normal country. They are led by LUNATICS."
