WASHINGTON, MAY 5: US Defense Secretary Pete Hegseth said on Tuesday that the ceasefire with Iran was not over, even as the US and Iran exchanged fire in the Gulf as they wrestled for control of the Strait of Hormuz.

Hegseth said the US had successfully secured a path through the critical waterway and that hundreds of commercial ships were lining up to pass through, as Washington seeks to break a chokehold Iran has asserted on the Strait of Hormuz since the conflict began on February 28.

“We know the Iranians are embarrassed by this fact. They said they control the strait. They do not,” Hegseth told a Pentagon news conference.

The US military says it sank six Iranian small boats and intercepted Iranian cruise missiles and drones, after President Donald Trump sent the navy to escort stranded tankers through the Strait of Hormuz in a day-old campaign he called “Project Freedom.”

Several merchant ships in the Gulf reported explosions or fires on Monday, the first day of the operation.

General Dan Caine, the chairman of the Joint Chiefs of Staff, said Iran attacked Oman once on Monday and waged three attacks on the United Arab Emirates, before adding that, at least so far, “today is quieter.”

Caine said that since the ceasefire was announced on April 7, Iran had fired at commercial vessels nine times and seized two container ships. Iran has attacked US forces more than 10 times, he added.

However, the attacks fell “below the threshold of restarting major combat operations at this point,” Caine told reporters.

Asked whether the ceasefire with Iran still held, Hegseth said: “No, the ceasefire is not over.”

“We said we would defend and defend aggressively, and we absolutely have. Iran knows that, and ultimately, the president can make a decision whether anything were to escalate into a violation of a ceasefire,” he said.

Blockade

The operation is Trump’s latest effort to force an end to the disruption of international energy supplies caused by Iran’s blockade of the strait, which carried a fifth of global oil and liquefied natural gas before the war.

The US Navy is also enforcing a maritime blockade of Iran, which prevents ships from going to Iran or departing Iranian territory.

The two military operations seek to pressure Iran to strike a deal to end the conflict on Trump’s terms. But Iran has countered that there is no military solution to the crisis, and it has threatened to fight for as long as necessary.

The US military said on Monday two US merchant ships made it through the strait, with the support of Navy guided-missile destroyers.

Iran denied any crossings had taken place, though shipping company Maersk said the Alliance Fairfax, a US-flagged ship, exited the Gulf under US military escort on Monday.

Caine estimated 22,500 mariners embarked on more than 1,550 commercial vessels were stuck in the Gulf, unable to transit.

“CENTCOM, along with partner nations, is in active communication with hundreds of ships, shipping companies and insurers,” Hegseth said, referring to the US military’s Central Command, which leads operations in the Middle East.

“All of these ships from all around the world want to get out of the Iranian trap that they have been stuck inside.”
