After heavy resistance from Islamic State militants in Tikrit, Iraqi forces were forced to retreat from the city, a blow that will further demoralize government’s hopes to push back the insurgents controlling large parts of the country.

Militants affiliated with Islamic State had seized Mossul, Tikrit and some other cities last month and the Al-Maliki government has been struggling ever since to recapture those cities from the insurgents.

The latest setback came as Iraqi politicians named a moderate Sunni as speaker of the parliament. World community had been pressing Noor Al-Maliki from a long time to form a coalition government with Sunnis and Kurds. However, Maliki government had repeatedly shunned the idea.

It is unclear if the election of Salim al-Jabouri as speaker will break the broader deadlock over Prime Minister Nuri al-Maliki’s bid to serve a third term. He has ruled since the April election as a caretaker.

Government troops and allied Shi’ite volunteer fighters retreated from Tikrit before sunset on Tuesday to a base four km (2.5 miles) south after coming under heavy mortar and sniper fire, a soldier who fought in the battle said.

Residents said there was no fighting on Wednesday morning in Tikrit, which lies 160 km (100 miles) north of Baghdad. It is a stronghold of ex-army officers and loyalists of executed former dictator Saddam Hussein’s Baath Party who allied themselves with the Islamic State-led offensive last month.

Tuesday’s military attack was launched from Awja, Saddam’s birthplace some 8 km (5 miles) south of the city, but ran into heavy opposition in the southern part of the city.

Pictures published on Twitter by supporters of the Islamic State showed a fighter holding a black Islamist flag next to a black armored car it said had been abandoned by a military SWAT team, as well as vehicles painted in desert camouflage – one of them burnt out – which it said retreating troops left behind.

MALIKI’S FUTURE UNCLEAR

The stunning advance in the north and west by the militants over the past month has put Iraq’s very survival in jeopardy, as its politicians remain divided over forming a government to confront the insurgency. A shared resentment at Maliki’s style of rule, which his critics say has marginalized Iraq’s Sunnis and Kurds, may have bolstered the Islamic State’s offensive last month.

The Shi’ite leader has defied demands from Sunnis and Kurds that he step aside for a less polarizing figure. He also faces challenges from within the National Alliance, a Shi’ite umbrella group that includes Maliki’s State of Law bloc and rivals.

After quickly picking Salim al-Jabouri as speaker on Tuesday afternoon, lawmakers argued bitterly for hours over his Shi’ite deputy, suggesting they are still far from a deal to complete the formation of a new government or a decision on the fate of Maliki.

Now that parliament has picked a speaker, it has 30 days to elect a president, who will then have 15 days to nominate a prime minister.

Since Iraq’s post-Saddam constitution was adopted in 2005, the prime minister has always been a member of the Shi’ite majority, the speaker a Sunni and the largely ceremonial president a Kurd. Each of the three is meant to have two deputies, drawn from the other two groups.

An official from Maliki’s State of Law bloc said the group understood that it would not be able to push through Maliki’s nomination for a third term and there was a need for “transition”, but did not say how that might come about.

Maliki has given no indication he is willing to step aside.

“Prime Minister Maliki can’t and shouldn’t be pushed out,” the official told Reuters, adding there had been no formal discussion yet on possible nominees for prime minister.

In the town of Dhuluiya southeast of Tikrit, where Sunni tribesmen and local police have been fighting militants for days, government forces sent from the city of Samarra pushed the militants out on Tuesday night, eyewitnesses said.

Islamic State gunmen had overrun government offices on Sunday morning and tried to take the main police station, local police and eyewitnesses said. The town is 70 km (45 miles) north of Baghdad.

Residents escaped the fighting by boat on the River Tigris after militants bombed the bridge and blocked off roads leading out of the town. The destruction of the bridge also blocked the sending of reinforcements from the military base near the Shi’ite town of Balad, across the river.

Control of Dhuluiya has passed several times from local fighters and police into the hands of militants and back again.
