Live updates: Trump says Iran operations likely to last 4 to 5 weeks

The after effects of the massive weekend attack on Iran are continuing as the Islamic Republic’s leadership is still in limbo and President Donald Trump says the operation could go on for weeks. 

The conflict has intensified into a wider war in the region. Iran and its allied armed groups have launched missiles at Israel, Arab states and U.S. military targets in the Middle East.

Meanwhile:

The Associated Press reported that at least 555 people have been killed in Iran so far by the U.S.-Israeli campaign. Four American service members had died, according to the U.S. Central Command, and Trump predicted over the weekend there would be more U.S. casualties.

Here are the latest updates from Monday:

President Trump first public remarks

11:45 a.m. ET - President Trump spoke publicly Monday morning for the first time since the massive weekend attack on Iran, saying the operations were likely to last 4 to 5 weeks but that he was prepared "to go far longer than that."

He laid out the Trump administration’s objectives for the operation: to destroy Iran’s missile capabilities, to "annihilate" their navy, to ensure the country doesn’t obtain a nuclear weapon and that the regime "cannot continue to arm, fund and direct terrorist armies outside of their borders."

"Today," he added, "we grieve for the four heroic American service members who have been killed in action and send our love and support to their families. In their memory, we continue this mission with ferocious, unyielding resolve to crush the threat this terrorist regime poses to the American people."

Hegseth speaks: ‘This is not endless’

8:45 a.m. ET: Defense Secretary Pete Hegseth and Joint Chiefs of Staff Chairman Air Force Gen. Dan Caine held the Trump administration’s first news briefing since Saturday’s strikes.

Hegseth spoke to widening concerns the strikes could spiral into a protracted regional conflict by declaring, "This is not Iraq. This is not endless." 

Hegseth said the operation have a "clear, devastating, decisive mission" to "destroy the missile threat" from Iran, destroy its navy and "no nukes." 

Asked if there are currently boots on the ground in Iran, he said, "No, but we’re not going to go into the exercise of what we will or will not do." He said it was "foolishness" to expect U.S. officials to say publicly "here’s exactly how far we’ll go."
