US forces ​began launching strikes against ​multiple targets ​in Iran on Wednesday, according to an X post by the US Central Command. 

The resumption of US attacks is a result of the downing of a US Apache helicopter in the Strait of Hormuz by Tehran.

Trump told reporters earlier on Wednesday at the White House, "We're going to ​be attacking them, attacking them very hard."

After the US launched the attacks, Iran responded by closing the Strait of Hormuz. 

"Effective immediately, due to insecurity in the region, the Strait of Hormuz is declared closed to all vessels, including oil tankers and commercial ships,”the IRGC said in a post on its official Telegram. "Any vessel attempting to transit the strait will be targeted."
