A couple of Iraqi asylum seekers are among a group of seven young men arrested after sickening video footage emerged in Belgium of an unconscious 17-year-old girl being gang-raped while the men danced around her, singing in Arabic.

Police say the girl was plied with vodka and doesn't remember what happened.

Four men and three boys between the ages of 14 and 25 were arrested -- two Belgians and five Iraqi immigrants, including the pair of recent refugees.

The attack happened at a home in Ostend in November but only recently came to light.

A teacher alerted police to a student's Facebook post -- a photo of the boy dressed in fatigues, posing with a gun. Fearing the boy had become radicalized, police spoke to the student and took his phone. That's when they found the video.

According to local reports, most of the accused have confessed. Some reportedly claimed the girl had given consent, but many of them shrugged off the shocking attack.

"She can't complain. Women must obey men," one reportedly told police.

The disturbing footage reportedly shows the group laughing and dancing around the victim, passed out on a bed. The men then pull down her underwear, push her legs apart, grope and take turns raping her.

Belgium's secretary of state for refugees and migrants, Theo Francken, told reporters the case is "disgusting" and said any refugee found guilty will be deported.

"The suspects will be prosecuted. If they are convicted they will have to serve their sentences. When they're released, there is probably no other option than to turn them back (to their home countries) to suffer," he told Belgium TV station VRT.

Belgium has been overwhelmed with Iraqi and Syrian refugees.

On Friday, the government approved a plan to combat Islamic radicalism and the threat of extremist violence by hiring 1,000 new police officers over the next four years.
