A denior State Department official has told ITV News that he US administration is "open to engaging the Iranians".
We are open to engaging the Iranians, just as we are engaging other regional players on the threat post by ISIL in Iraq.
The issue did come up briefly with Iran on the margins of the P5+1 in Vienna today, separate from our trilateral meeting.
These engagements will not include military coordination or strategic determinations about Iraq’s future over the heads of the Iraqi people.
We will discuss how ISIL threatens many countries in the region, including Iran, and the need to support inclusivity in Iraq and refrain from pressing a sectarian agenda.
The Foreign Secretary has been clear on the threat of Isis, but he has ruled out the prospect of any UK military involvement in the crisis.
Iraq’s foreign minister, Hoshyar Zebari, is a natural diplomat. Polite, immaculately dressed, and blessed with a great memory.
Isis has paraded military equipment in Mosul it captured from when the Iraqi army fled in what some see as a "nightmare scenario."
