The US Senate majority leader Harry Reid has refused to back any potential plans to send American troops into conflict in Iraq, calling the situation a "civil war."
"I do not support in any way putting our men and women in the midst of this civil war in Iraq. It is not in the national security interest of our country," Reid said in remarks opening the Senate's daily session.
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."
