Heavy clashes as Iraqi forces push into militant-held Fallujah

Iraqi forces battling their way into Fallujah have repelled a four-hour counter-attack by the Islamic State group '“ a day after entering the southern part of the militant-held city with the help of US-led airstrikes.

A leading aid group meanwhile raised alarm over the unfolding “human catastrophe” in Fallujah, where an estimated 50,000 people remain trapped, and renewed calls on warring parties to open up safe corridors for civilians to flee.

The dawn attack on Tuesday unfolded in Fallujah’s Nuaimiya area, most of which was captured by Iraqi troops the previous day, two special forces officers said.

IS militants used tunnels and snipers, and targeted Iraqi forces with six explosives-laden cars that were destroyed before reaching their targets, the officers said. Iraqi forces suffered casualties, but the officers didn’t provide details.

The officers said progress was slowed by roadside bombs planted by militants. The troops also paused to destroy tunnels in the area. The officers said 106 militants have been killed since Monday.

Fallujah was the first Iraqi city to fall to IS and is the last major urban area controlled by the extremist group in western Iraq. The militants still control the country’s second largest city, Mosul, in the north.

The US-led coalition and Iranian-backed Shiite paramilitary forces are helping the Iraqi army in the battle to retake Fallujah. But the fight is expected to be protracted, as the militants have had more than two years to dig in. Tens of thousands of civilians remain trapped in Fallujah and hidden bombs are believed to be strewn throughout the city.

“A human catastrophe is unfolding in Fallujah,” Jan Egeland, the head of the Norwegian Refugee Council said, adding that only one family managed to escape from the town on Monday. Since the offensive began a week ago, 554 other families have escaped from areas surrounding Fallujah, which lies 40 miles west of Baghdad.

“Warring parties must guarantee civilians safe exit now, before it’s too late and more lives are lost,” Egeland added. The NRC said a lack of food, medicine, safe drinking water and electricity in the city is “pushing families to the brink of desperation”.

The spokesman of the UN refugee agency, William Spindler, said 624 families – or around 3,700 individuals – have fled over the past week, citing figures by Iraqi authorities.

Spindler said the UNHCR “understands another 500 men and boys over 12 years old are held for security screening” which can take five to seven days. “We understand some 27 men were released” on Monday, he said.
