Iraq Presses Fightback after Breaking Jihadist Siege

Iraqi troops, Kurdish fighters and Shiite militiamen backed by U.S. air strikes pressed a fightback against jihadist-led militants Monday, buoyed by breaking a weeks-long siege of a Shiite town.

The military gains came as a senior U.N. rights official said the Islamic State (IS) jihadist group has carried out "acts of inhumanity on an unimaginable scale" in Iraq, while caretaker premier Nuri al-Maliki vowed the country would prove the group's "graveyard".

The breakthrough to the town of Amerli on Sunday was the biggest offensive success for the Iraqi government since IS-led militants overran much of the Sunni Arab heartland north and west of Baghdad in June.

The United States carried out limited air strikes in the area during the operation, the first time it has expanded its more than three-week air campaign against IS beyond the far north of Iraq.

Iraqi forces kept up the momentum on Monday, with Kurdish peshmerga fighters and Shiite militiamen retaking Sulaiman Bek, a town north of Amerli that had been an important militant stronghold.

"Within a few hours, we were able to clear the town completely," the commander of the Shiite Badr militia, Transport Minister Hadi al-Ameri, told AFP amid heavy security in Sulaiman Bek.

Fighters celebrated in the abandoned town, firing in the air, chanting slogans against IS and showing off a captured black flag of the group, an AFP journalist reported.

Troops backed by Kurdish fighters and Shiite militiamen also surrounded the nearby town of Yankaja and pounded it with artillery and machine-gun fire as they fought to retake it from militants.

Before the operation, the mainly Shiite Turkmen residents of Amerli were endangered both because of their faith, which jihadists consider heresy, and their resistance to the militants who besieged the town for 11 weeks.

U.N. Iraq envoy Nickolay Mladenov had warned that they faced a "massacre" by the besieging militants.

Maliki visited Amerli, 160 kilometers (100 miles) north of Baghdad on Monday, vowing that "Iraq will be a graveyard" for IS.

The operation to break the siege of the town was launched on Saturday after days of preparations.

The government's reliance on Shiite militiamen in this and other operations risks entrenching groups which themselves have a history of brutal sectarian killings.

The United States said it had carried out a total of four air strikes in the Amerli area, expanding its air campaign outside northern Iraq.

In doing so, it is supporting operations involving militia forces which previously fought against U.S. troops in Iraq.

David Petraeus, a former commander-in-chief of U.S.-led forces in Iraq, has warned against America becoming an "air force for Shiite militias".

Meanwhile, more pledges were made to provide arms to Iraq's Kurds, who are battling jihadists in northern and eastern Iraq.

Backed by U.S. air strikes, Kurdish troops have succeeded in clawing back some areas of the north that they lost to the jihadists last month.

Germany will send anti-tank rocket launchers, rifles and hand grenades to support Kurdish forces, the German defense ministry announced.

Chancellor Angela Merkel made an impassioned 25-minute speech Monday in support of arming the Kurds, saying: "We have the opportunity to save lives and stop the further spread of mass murder in Iraq."

She also said an estimated 400 German nationals had traveled to Iraq and Syria to fight alongside jihadists, and that "we must fear these fighters could return one day."

The issue has raised fears in various Western countries, and British Prime Minister David Cameron was on Monday due to outline tougher measures against suspected jihadists.

The United Nations mission to Iraq said on Monday that violence in the country killed at least 1,420 people during August and wounded a further 1,370.

It said the figures did not include Anbar province, west of Baghdad, acknowledging difficulties in verifying information from conflict zones and areas outside government control.

IS and its allies control a large swathe of northeastern Syria as well as territory in Iraq, and its rule has been marked by atrocities that have shocked the world.

"The reports we have received reveal acts of inhumanity on an unimaginable scale," deputy U.N. rights chief Flavia Pansieri said Monday.

Washington has said that operations in Syria will be needed to defeat IS, but has so far ruled out any cooperation with the Damascus regime against the jihadists.
