Iraq's Mahdi Army - a powerful Shia militia that fought British and American troops in Iraq - has reformed to fight the Sunni insurgents now threatening to overrun the country.
Hundreds of armed men paraded through Baghdad and Kirkuk this morning. They are followers of the cleric Muqtada al-Sadr, who disbanded them in 2008 after years of fighting the Iraqi government and coalition troops.
They've now answered a call from al-Sadr to reform to defend Iraq's holy places from the ISIS insurgents.
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."
