Iraqi military forces reached the center of the northern city of Baiji on Sunday to try to break an Islamic State of Iraq and Syria (ISIS) siege of the country’s biggest refinery nearby, triggering fierce clashes with the militants, according to an army colonel and a witness.

ISIS insurgents seized Baiji city in June during a lightning advance through northern Iraq. Since then, they have surrounded the refinery and halted its production while a detachment of government troops has held out for months under siege inside it.

The colonel said Iraqi troops entered Baiji, a city of about 200,000 people, from the south and west and took over the al-Tamim neighborhood and city center.

ISIS had placed bombs along roads in Baiji and deployed snipers to keep government forces from advancing, tactics used in other cities held by the ultra-hardline Sunni group, which controls swathes of both Iraq and Syria.

“There are IEDs (improvised explosive devices) and snipers that are slowing down the advance, but the presence of the air force has facilitated the process of dismantling the IEDs in order to push forward,” said the colonel.

“The areas taken so far are 6 km (3 miles) away from Baiji’s refinery,” he added. He said 12 militants had been killed.

Baiji resident Sultan al-Janabi told Reuters by telephone from his house that clashes had been raging since the advance, the first time security forces reached the city center since launching a new encirclement strategy at the end of last month.

“Violent confrontations are taking place in Baiji right now. I’ve been hearing continuous fire and loud bangs,” said Janabi.

ISIS has also dispatched suicide bombers to keep security forces on the defensive.

Police general killed

On Friday night, a suicide bomber rammed a truck packed with explosives into a Humvee transporting senior police commander General Faisal Malik, one of the supervisors of the campaign against ISIS militants surrounding the refinery. The general and two policemen were killed.

The truck used in the attack was armored, the army colonel and a provincial police command center said, suggesting ISIS had seized it from defeated Iraqi troops. Tanks and anti-aircraft weapons have also been taken.

The army colonel estimated that Iraqi forces had taken about 40 percent of the city center. That could not be independently confirmed.

Iraqi security forces have used helicopters to attack ISIS insurgents surrounding the refinery.

But months of operations have failed to rescue comrades trapped inside and ensure the strategic site will not fall into the hands of ISIS, who have used oil and fuel to fund their self-proclaimed caliphate.

Iraqi oil industry officials estimate ISIS is making multi-million dollar profits from the illegal trade.

Late last month, Iraqi government forces tried a new approach. Backed by Shi’ite Muslim militias and helicopter gunships, they circled Baiji from the west in order to retake the city and cut off supply lines to insurgents surrounding the refinery a few km (miles) away.

Government forces, including counter-terrorism units, inside the compound have been surviving on airdrops as military forces outside tried to drive ISIS militants away.

The Baiji refinery was producing around 175,000 barrels per day before it was closed, a senior Iraqi official said in June. Iraq’s domestic daily consumption is estimated at 600,000-700,000 bpd.

If the siege of the Baiji refinery is broken, Iraq’s government is likely to describe it as a major victory over ISIS. Iraqi media portrayed the slain general, Malik, as a hero.

The country’s long-term stability hinges on efforts to dramatically improve the performance of the army, which crumbled when ISIS swept through the north.

The United States, which fought ISIS’ predecessor al-Qaeda during the American occupation of Iraq, will send up to 1,500 more troops to train Iraqi forces. Britain also plans to send trainers.
