22 Iraqi soldiers and fighters killed from the Shiite Popular Mobilisation Forces in a double suicide car bombing by ISIS in east Fallujah, local police sources told Al Jazeera.
The twin car blasts targeted a congregation of Iraqi army soldiers and fighters. At least 24 were also wounded in the incident.
The cars were a stolen Iraqi army Humvee and an armoured army vehicle at the Harariyat village, part of Al Karmah town, Fallujah.
"Iraq's security forces are taking towns and villages surrounding those cities and use them as staging posts to go into Ramadi and Fallujah," said Al Jazeera's correspondent Imran Khan, reporting from Baghdad.
"However, we have spoken to the hospital sources who say that at least six civilians were killed in that attack," said Khan.
Khan also said that Iraq's air force carried out air strikes in the centre of Fallujah, hitting a mosque that was allegedly housing ISIS fighters. At least 17 of the fighters were reportedly killed in the attack.
Sunni residents of the targeted cities have reportedly been advised to move out so they won’t be mixed up with ISIS fighters and mistakenly targeted.
"One of the sources said that it doesn't matter even if they are women and children. If they are still in Ramadi, for example, at the time when the rival forces go in, they will be seen as ISIL [ISIS] supporters," Khan said.
ISIS has control over Mosul, Iraq’s second largest city along with Fallujah and Ramadi. With large swaths of Syria comprising roughly 50 percent of the country.
The fall of Iraq’s Ramadi was considered a big setback in the war against ISIS in the region.
