WASHINGTON/TEHRAN - US President Donald Trump said on Friday that the US military campaign in Iran will last "as long as necessary."

When asked by reporters how long the war will last, he said: "I can't tell you that."

"I won't give you a time, but we are way ahead of schedule," he added. 

Kharg Island 

Military targets in Iran's Kharg Island have been "totally obliterated" in US bombing raids, Trump said Friday on Truth Social. 

Strait of Hormuz 

The United States will not allow shipping in the Strait of Hormuz "to be contested" by Iran, US Defense Secretary Pete Hegseth said Friday.

There is no clear evidence that Iran has placed mines in the Strait of Hormuz, he said at a news briefing.

He said the United States is planning for Iran's various measures and "that's not a strait we're gonna allow to remain contested."
