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 

Trump said Friday that the US military carried out bombing raids against military targets on Iran's Kharg Island, a key oil export hub that handles most of the country's crude shipments.

Via his Truth Social account, Trump also said he had decided not to strike the island's oil infrastructure, although he would change his mind "should Iran, or anyone else, do anything to interfere with the free and safe passage of ships through the Strait of Hormuz."

Citing experts, CNN reported that any attempt to capture Kharg Island would require a substantial number of ground troops, something the Trump administration has so far been reluctant to commit.

Kharg Island lies in the Persian Gulf about 25 km off Iran's coast and accounts for about 90 percent of the country's crude exports.

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."

More than 50,000 US service members are involved in the military strikes against Iran, a senior Pentagon official said Friday.

The US Central Command on Thursday reported about 6,000 targets struck, with more than 60 ships and 30 minelayers damaged or destroyed, the post added.
