Trump says more US attacks on Iran 'highly unlikely'

Donald Trump has said "Iran militarily is effectively over", and said that there is "positive momentum" behind negotiations to end the Middle East conflict.

"We're just keeping it the status quo," the US president said on Monday. "And we're doing that really at the behest of countries that are their neighbours."

Addressing reporters from the White House press briefing room, Trump said that renewed US attacks on Iran were "highly unlikely" but that the US was "locked and loaded" should the circumstances change.

Iranian officials have repeatedly expressed doubts about Trump's prior comments about resolving the conflict.

This is not the first time that Trump has said the Iran war is "militarily" over, but the circumstances for him are different now.
