Sunni insurgents led by an al-Qaida breakaway group expanded their offensive in a volatile western province on Saturday, capturing two strategic towns and the first border crossing with Syria to fall on the Iraqi side.
It's the latest blow against Prime Minister Nouri al-Maliki, who is fighting for his political life even as forces beyond his control are pushing the country toward a sectarian showdown.
In a reflection of the bitter divide, thousands of heavily armed Shiite militiamen - eager to take on the Sunni insurgents - march through Iraqi cities in military-style parades on streets where many of them battled U.S. forces a half decade ago
The towns of Qaim and Rawah are the first territory seized in Anbar province, west of Baghdad, since fighters from the Islamic State of Iraq and the Levant group overran the city of Fallujah and parts of the provincial capital of Ramadi earlier this year.
Sunni militants have carved out a large fiefdom along the Iraqi-Syrian border and have long traveled back and forth with ease, but control over crossings like that one in Qaim allows them to more easily move weapons and heavy equipment to different battlefields. Syrian rebels already have seized the facilities on the Syrian side of the border and several other posts in areas under their control.
Police and army officials said Saturday that the Sunni insurgents seized Qaim and its crossing, about 320 kilometers (200 miles) west of Baghdad, after killing some 30 Iraqi troops in daylong clashes Friday.
The officials, who spoke on condition of anonymity because they were not authorized to talk to journalists, said people were now crossing back and forth freely.
Chief military spokesman Lt. Gen. Qassim al-Moussawi acknowledged Qaim's fall, telling journalists that troops aided by local tribesmen sought to clear the city of "terrorists."
Sunni militants also captured the Euphrates River town of Rawah, ransacking government offices and forcing local army and police forces to pull out, Mayor Hussein AIi al-Aujail said. The town, which had remained under government control since nearby Fallujah fell, also lies dangerously close to an important dam near the city of Haditha.
Military officials said more than 2,000 troops were quickly dispatched to the site of the dam to protect it against a possible attack by the militants. They spoke on condition of anonymity because they were not authorized to speak to the media.
