Sunni Islamist militants have advanced on more towns in eastern Iraq. Prime Minister Nouri al-Maliki's Shiite-led government in Baghdad appears paralyzed. Kurds in northern Iraq have asserted more control over Kirkuk.
Sunni militants calling themselves the Islamic State of Iraq and Levant (ISIS) had moved into two towns in the eastern province of Diyala by early Friday, intent on advancing further toward the city of Baquba, the region's ethnically-mixed capital.
Police quoted by the news agency Assocated Press said militants driving pickup trucks had entered the towns of Jalula and Sadiyah overnight after Iraqi soldiers allegedly abandoned their posts.
Army officers quoted by the news agency AFP said government forces were, however, battling insurgents in Muqdadiyah, 35 kilometers (23 miles) northeast of Baquba, which in turn lies just 50 kilometers north of Baghdad.
Greatest instability since 2011?
The developments signal what could be Iraq's greatest instability since the United State's 2011 troop withdrawal. On Thursday, Maliki's Baghdad government appeared paralyzed when parliamentarians denied him a quorum and power to declare an emergency.
Witnesses said countless vehicles carrying militants had also gathered near the city of Samarra, which has a revered Shiite shrine.
That coincided with evacuations from Balad in northern Iraq of planeloads of Americans, including employees of the US arms firm Lockheed Martin Corp.
Lockheed said its employees had been working with the Iraqi air force as it prepared to receive the first of 36 F-16 fighter jets due later this year.
Zebari admits setback
Referring to the insurgents'capture on Tuesday of Iraq's second-largest city Mosul,
Iraqi Foreign Minister Hosyhar Zebari acknowledged that the security forces had melted away, despite the billions invested in them by Washington up to 2011.
"It is a setback definitely for the Iraqi security forces, who collapsed in the largest city and abandoned their weapons and equipment," Zebari told AFP.
So far, the militants have stuck to Iraq's Sunni heartland and strongholds, including Tikrit, the hometown of the late dictator Saddam Hussein.

Hundreds of young men crowded in front of an army recruitment center to volunteer to fight the insurgents.
Shiite cleric Muqtada al-Sadr and the Asaib Ahl al-Haq Schiite militia vowed to defend Schiite shrines, raising the specter of street clashes.
Kurds use power vaccuum
Kurds, who run their own autonomous region in Iraq's north, used a power vaccum left by government forces departing bases in Kirkuk on Thursday to fulfill a decades-long ambition to extend Kurdish control to the oil-rich city.
The region's deputy governor, Furat al-Tamimi, said on Friday Kurdish security forces had moved into the strategic Saadiyah and Jalawla districts of Diyala province after the army withdrew.
Turkey still seeking releases
Turkey said it was still holding talks to secure the release of 80 of its citizens kidnapped by Islamist militants, mainly in Mosul, amid international calls for their release.
The UN Security Council demanded urgent dialogue and condemned "terrorist" activities, but stopped short of considering action against the militants.
