Islamic militants have captured Iraq's northern capital, Mosul, in a devastating defeat for the Iraqi Government, whose forces fled the city, discarding weapons and uniforms.
The victory by the Islamic State of Iraq and Syria (Isis) is likely to transform the politics of the Middle East as foreign powers realise that an al-Qaeda-type group has gained control over a large part of northern Iraq and northern Syria.
The US said it supported a "strong, co-ordinated response to push back against this aggression".
An Iraqi army colonel admitted: "We have lost Mosul this morning. Army and police forces left their positions and Isis terrorists are in full control."
As well as police stations, army bases and the airport, the insurgents have captured two prisons and freed 1200 prisoners, many of them Isis fighters. Roads out of Mosul are choked with refugees heading for what they hope is safety in Kurdish-held territory.
