US secretary of state John Kerry said it is a critical moment for Iraq's future and it is urgent that Iraq's leaders come together and stand united against militants.
America's support for Iraqi security forces will be "intense and sustained," he said, speaking at a press conference in Baghdad.
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."
