what did the u.s. do to iran when a singaporean ship was attacked

The U.S. launched military strikes against Iranian targets after the attack on the Singapore-flagged cargo ship in the Strait of Hormuz. Reported targets included missile and drone storage sites plus coastal radar sites.

What happened

Iran was reported to have attacked the ship with drones, and the U.S. response came the next day as retaliation. One report says the ship was the M/V Ever Lovely, and that the incident was treated as a serious violation of the ceasefire.

U.S. response

• Air or military strikes against Iranian targets.

• Hits on missile and drone storage locations.

• Strikes on coastal radar sites.

Context

The attack mattered because it involved a Singapore-flagged commercial vessel in a major shipping corridor, so the U.S. framed its response as defending freedom of navigation. President Trump also described the strike on the ship as a ceasefire violation.

TL;DR: After the Singapore-flagged ship was attacked, the U.S. retaliated by striking Iranian missile, drone, and radar sites.
