BAGHDAD — Kurdish forces attacked Islamic State fighters on Wednesday just 40 km southwest of the Kurdish regional capital of Arbil in northern Iraq, a senior Kurdish official told Reuters.



The attack came after Islamic State militants inflicted a humiliating defeat on the Kurds on Sunday with a rapid advance through three towns, prompting Iraq’s prime minister to order his air force for the first time to back the Kurdish forces.



“We have changed our tactics from being defensive to being offensive. Now we are clashing with the Islamic State in Makhmur,” said Jabbar Yawar, secretary general of the ministry of the Kurdish peshmerga fighters.



The location of the clashes puts the Islamic State militants closer than they have ever been to the Kurdish semi-autonomous region since they swept through northern Iraq almost unopposed in June.



Shortly after that lightning advance, thousands of US-trained Iraqi soldiers fled. Kurdish fighters, who often boast of their battles with Saddam Hussein’s forces, stepped in as did Iranian-trained Shiite militias.



Yawar said the Kurds had re-established military cooperation with Baghdad. Ties had been strained between the Kurdish leadership and the Shi’ite-led government of Prime Minister Nouri Al-Maliki over oil, budgets and land.



But the dramatic weekend offensive by the Sunni militants — who seized more towns, a fifth oilfield and Iraq’s biggest dam — prompted them to bury their differences. “The peshmerga ministry sent a message to the Iraqi defense ministry requesting the convening of an urgent meeting on military cooperation. The joint committees have been reactivated,” said Yawar by telephone.



The Islamic State, which has declared a ‘caliphate’ in swathes of Iraq and Syria that it controls and threatens to march on Baghdad, poses the biggest threat to OPEC member Iraq since a US-led invasion toppled Saddam in 2003.



Islamic State fighters and their Sunni militant and tribal allies also hold parts of western Iraq.



Efforts to neutralise the Islamic State have been undermined by political deadlock and sectarian tensions fueling levels of violence not seen since the height of a civil war in 2006-07.



Critics say Maliki is an authoritarian leader whose sectarian agenda has sidelined Sunnis and driven them to find common cause with the Islamic State, even though they reject the group’s radical view of Islam.



Maliki, who has been serving in a caretaker capacity since an inconclusive election in April, has rejected calls by Kurds, Sunnis, some fellow Shiites and even regional power-broker Iran to step aside and make room for a less polarizing figure. He remained defiant on Wednesday in his weekly televised address to the nation, warning any unconstitutional attempt to form a new government would open “the gates of hell” in Iraq.



Maliki rejected any outside interference in the process, an apparent reference to Tehran, which Iranian officials have said believes Maliki can no longer hold Iraq together.



Iran is now backing calls by Iraq’s top cleric Grand Ayatollah Ali Al-Sistani for Maliki to go and is looking for an alternative leader to combat the insurgency, said the Iranian officials.



The United States, which was a key backer of Maliki when he fist came to office as an unknown in 2006, has urged Iraqi politicians to form a more inclusive government that can unify Iraqis and take on the Islamic State. — Reuters
