DUBAI, United Arab Emirates (AP) — The U.S. military said Saturday it had struck multiple targets in Iran at President Donald Trump's direction, continuing a string of attacks that have shaken the war's uneasy ceasefire.

U.S. Central Command, in a post to social media, said that U.S. military aircraft targeted Iranian military "surveillance infrastructure, communication systems, air defense sites, drone storage facilities, and minelayer capabilities" following an attack on a merchant vessel early on Saturday morning.

The ongoing strikes in the Persian Gulf show the danger of the Iran war again spinning out of control, even after Iran and the U.S. reached an interim deal to try and agree on a final accord to end the conflict.

The incident follows a similar back and forth that occurred just days prior when an Iranian drone struck a merchant vessel off the coast of Oman on Thursday and the U.S. military retaliated with strikes the next day.
